TRUE LOVEHay guys this time I'm posting stories niich hopefully stories of our friends made it fun yes Cahya Nuraini

 
Why must you there before me now? why is not he who is already in my heart since the first? I'm sorry I used to have to hate you, because maybe now it's karma for me. Forgive me, leave me, give me a first love. Not him god .....Vaguely I open my eyes had been blinded by the radiant sun because of the window. Apparently Mbok figure that has been taking care of the child.
"Good morning non.""Mbokk morning,,,""Mistress waiting for breakfast non""Iia mbok, thank you" ..My name is valentina cicilia nugraha, I was born just in time for Valentines Day because I always brhrap Yamada got the love from everyone. It's true, life is almost perfect. I'm a pretty smart kid not stupid-stupid yah lah very rough terms. Having parents who love me, abundant wealth, a beautiful face, a lot of friends, and lots of guys who like. Right now I'm in a relationship with someone, he's my schoolmate named dani. Sejujurya I do not really love him, but in the popular kid in school because he's cool for sure and because pressure from my friends to be willing to accept dani a boyfriend, then I will establish a relationship with him, had hmpir 4 months and now I have one high school grade."Morning dear,," said my mother at the dinner table."Morning ma, papa where?""No meeting your father, so it should go ahead.""Ohh .." both of us breakfast but soon .......... "Morning ....!" Courtesies that sounds familiar to me. Yes, the dani is like a personal driver for me. Wherever I go he's ready to deliver. In fact he was willing to drive each morning pick me up."Morning dear," said my mother.
     
He also kissed me on both cheeks and berslaman to mama. They are quite familiar, and there is no word shame. I even get scared if they have to continue the relationship into marriage with dani krna I did not really love him."Unfortunately today there are replicates, we leave right now, yes, because I have not learned" as stiff as before dani talk more with my mama."Oh, let's yaudah. Salim is mama GIH "we also went to school drove his car bmw, dani was the child so that he became the haves and the coolest kid in school most admired."Unfortunately, today there is reportedly a new student in my class.""Ohhh,,," I said cool, because I did not feel like talking to him."You what? sick, "he asked smbil trying to stroke my hair, but I dodged."I'm not okay, its just a little dizzy because of staying up semalem"."Ngapaen stay up? learn? ""Not really, I watch the ball". I replied to dampen the tense atmosphere in the car.Finally we arrived at the school."I love first, yes, I would nyamperin children first" I said "yes". We also split on the road to the school parking lot and I walk alone to the class, luckily I met my friends. Rani, bella and lia."Heyyy, wait" shouted"Ehhh, she is our daughter has come," joked the rani who is son goookill abizzz."Ihh, fuck sihh""Uh-uh, do not know, she says there's a new kid in class gue.katanya lohh heck of Java guy, I hope ajah saucy."
     
Lia who interrupted the child is really like ngeliatin aka handyman nyeleksi cwok. Nearly all the boys in this school he is known not only friends but also a force-grade boys 2 & 3.
"Already know how come from the dany" I replied."Lia if tuh be saucy for me. Cilla, we are today replicates the physics right? 've learned lo "asked bella to me.
     
I have not had time to answer the bell but it was in and we ended up running into the classroom.
     
At recess rang suddenly there is one friend who told me"Cilla Cilla, the dany fight behind the school" fikirku let alone, yet he was bruised ngrasaen, dani is the child of false bravado. Because of her many friends and an older class so he often looking for trouble dengana first graders. But I'm a girlfriend, so I have to ride at least absent dong! I will slide into the back of the school. Once until the beginning I let it go, to see who is in hajarnya this time and when I asked who got beat lia apparently is the new kid. I noticed the new face of the child because it is a familiar face to me and my new SJA realize it was Ali, my first love when I was in elementary school grade 5. Although in saying still small, but still no one succeeded him in my heart. Stunned, shocked but happy. Immediately, I ran and tried to break up fights this. To be honest all my friends surprised because I never aggressive to arbitrate disputes dany."Sudaaahh! stop "turned my face to face with dany dany emotion but it has not gone down sehigga me who exposed killer punch, soon I tersugkur fall. Dani deeply regret but still shocked to see me fall in contrast to the direct ali held me for trying to help me but was immediately pushed dany fall and keep him away from me. I passed out and did not remember anything else. But I still vividly remember the handsome face that was half surprised to see me just as I was surprised to see him.
     
Having realized that I had been in the room. And all my friends have gathered, I will call lia and asked to explain. "Lia, there was in fact what the hell?""That was the same annoyance dany ali the new kid, because he thought it was pretentious ali gandrungi cool and a lot of girls in the class. Yeah, I think anyway in dany began to lose competitiveness so deh, ali emang dany but not as rich as so many girls who ask nomernya. '"Including lo?' As rigid"Exact""May I ask?""For what?""Apologize for the treatment dany""Sembunyiin lo something from me ...""I have not time for li story, will you tell me for sure. Plisss do you know to dany ya! ""Sip"
     
After giving numbers lia ali, dany liapun exit and entry. But I pretended to faint. When dany has expressed regret and apologized he too told me to go home. When everyone had gone home I will not waste time and immediately phoned ali. I hesitated squeeze one by one number that. Tuttttt tuuuttt tuuuutt telephone connection that makes me sound a little shaky."Hallo!" Sound that had always remained unchanged in my ear. Sounds syang loving figure in my heart"Hello, ali" I tremble happy but tears dripping."Who are you?""You do not mngenalku again? it's me ""Cilla" but I'm speechless, it's like mouth could not say a word. "Cilaa, Cilla, answer me. Do not be silent cil, I miss your voice. ""I al. I was intending to meet you. Tomorrow in the school garden "after I closed telephone. I was relieved, I was happy and I cried. Tuhannn thank you, I know you love me god.
     
The next day I will meet with ali and existing park figure guy, waiting. High Bdannya strapping."Ali" I called softly and immediately sat down beside him. But he just looked at me with the."Why do you look at me like that?""Cilla unchanging beauty.""You crap ..""No,""You cool al,""Departure cil has transformed my attitude, you do not realize. Your leaving me shattered, without letters and word ""I do not bermaksut al, smpai now I still sayank you, my love never changed. Kedaan when it was difficult. Corporate bankruptcy daddy. I had to move several times to support the family economy. I also sadly can no longer communicate with you ". Silence blanketed the afternoon."Where love al? they lost it? '."I do not know ... lost years I was looking for and the only spirit that I have. What do you think. Indeed, we are still small, but it's different persaan cil. ""I know Al, but must you bestow keslahan that to me? little girl who does not know anything! "imperceptible grain nodes suddenly dripping and tears profusely."Do not cry cil, I did not mean to make you cry. I always lose and melted when seeing menngis "and immediately hugged me ali. He usapnya crystal clear in my cheek with his fingers loving syang. But it seems our bad day, dany suddenly appeared and wrong. Without length he told his friends to hold while dany ali beat. I try to hold it as best I can, but muscular hand I still unlucky to lose power. And I had to hug dany to dampen anger. He melted. I see ali disappointed. And immediately lowered her head."Hear ya lo bastards, never lo deketin my girl again. Once again I lo clay deketin my girl. Mampuss lo! ""If a girl lo deketin I do?"I startled bersma dany group. I also was surprised because Ali was able to say that, as if he did not try to protect me. "Ahhhh, tahikk lo .."in hajarnya ali for the second time."Sayank, already, not in ladeni this cowardly boy!"sarcastically cynical. Alipun like mennyesali words.
     
Tonight I was thinking about ali, sayings which I think is very, very painful. But suddenly there was a sound of knocking on the door."There are non""CWE cwo what?""Non guy"
     
Kufikir the dany but how surprised I was because it turns out that comes ali. Confused because I wanted to see what was not to be honest I'm still angry with him."Chatting in the park wrote al" I bete. I pimpim road ahead to get to the front garden. We then sat on a bench in the middle of the park. Mbok told me to fetch a drink for him. Shortly silent but ali berusha for fishing chat between us. "Still angry?""Still""I have to how""You should not biacara like that.""Afraid?""Mean?""Cnta it should be fearless. Knows no pain. "" I bukn tomboy who were aged 9 th al. I am 15 years old teen al. I've changed ""I know, but love is not it?""Forever only for you.""Would you still smpan it for me?""Just for you, and forever for you" slowly we hold both our lips, and slowly but we also touch the lips PstI. He gently creamed lips. And the first kiss on the forehead. Unfortunately at the time I forget that I already have an appointment to dany, lia, bella, and rani. They all saw what happened. "Lo son of a bitch!" New dany want to hit ali, I've been in depanya and again, I was exposed to punch in the head. But I try not to faint."Stop and. Nyadar not siih lo. During this same ignorant tuh me so lo lo dump me. I want to finish with GAX lo lo sick because I was afraid. Ali and my first love, because that's what I do not ever nganggap all my girlfriend loves me seriously because sebenrnya for Ali and Cuma. Plisss, ngertiin me, grow up a little and. If my dear lo, I relain ""Ok, lo win sob, I'm not going to disturb the relationship lo both again. We maen fair here "berlalulah dany."Ciehhhh, the Princess had finally found true love of the true love" crap rani"Ciehhh ... ciehhh" cried bella and lia. Tomorrow full nieh ....
     
Meriahlah atmosphere that night. Canda mirthful laughter. Hepi kusnendang yah guys. Hopefully my relationship lasting until grandfathers and grandmothers alike the ali i love .... hehehee. ..

Understanding CAPACITORS

Electronics components this time we will discuss is kapasitor.Selain capacitor's name was condensator.Komponen like resistors are also included in the group of passive components, the type of components that work without the need for bias current.
The types of capacitors are various, such as below.

* According to the Polarity
- Capacitors Polar
Polarity (+) and (-).
Polarity in the installation must be considered and should not be installed upside down. In a sign bodynya polarity to the polarity mark foot (+) or (-).
- Non Polar Capacitor (Capacitor Bipolar)
This capacitor type can be mounted back and forth.


* According to the Material Pembuatannya
The capacitor is basically two pieces of metal plate (dielectric) separated by a material Isulator. Well, here's the clincher material Isulator capacitor name.
According to the materials of manufacture jenis2 capacitor is:
- Electrolytic Capacitors → isulatornya made from electrolytic
- Capacitors Mika → isulatornya material made from mica
- Capacitors Air → isulatornya material made from the air.
- Paper Capacitors, Tantalum, mylar, etc..

* According to the assessment value is
- Capacitors Fixed / Permanent
Capacity value can not be changed.
- Variable Capacitors sometimes called VC or Varco (variable capacitor)
Capacitors of this type we can change the value to change.

The function of a capacitor is to store the current / voltage. For current DC capacitors serve as Isulator / retaining an electrical current, while AC current function as a conductor / passing an electric current.
In application is used as a filter capacitor / filter, rectifier voltage DC to AC to DC converters, ac wave generator or oscillator etc..

Capacitor value can be seen in the writings found on her body, for example, 10 uF/16 V means that the capacitor value is 10 micro Farad and can operate at maximum voltage of 16 V, if it exceeds 16 V, the capacitor will experience 'break down' aka ko'it :-).
Farad is the unit value of the capacity of the capacitor.
1 uF → 1 micro Farad = 1 x 10 ^ (-6) = 0.000001 Farad Farad
1 nF → 1 nano farad = 1 x 10 ^ (-9) Farad
1 pF pico Farad → 1 = 1 x 10 ^ (-12) Farad

# Code Number In Capacitors
For capacitors rated capacity below 1 uF capacity value normally written in code numbers.
Example:
1. 104 → 10 x 10 ^ 4 (in units of pico Farad) = 100000 pF or 100 nF or 0.1 uF
2. 222 → 22 x 10 to the power 2 (pF) = 2200 pF or 2.2 nF
* How are we rewrite the first two numbers, then we multiply by 10 to the last digit.
3. 4N7 → 4.7 nano farad
4. 2P5 → 05.02 pico Farad

Capacitors are uF value below 1 is generally non-polar type, except for the type of electrolyte.

IniDalam image below schematics capacitor is a capacitor electronics symbols are as under iniYang no sign (+) and (-) is a symbol of the non-polar capacitor while the (+) and (-) is a non-polar capacitor symbol.
CAPACITOR (Condenser)
Capacitors (capacitors) that the electronic circuit is denoted with the letter "C" is a device that can store energy / electric charge in an electric field, by collecting internal imbalance of electric charge. Capacitors discovered by Michael Faraday (1791-1867). Unit called the Farad capacitor (F). One farad = 9 x 1011 cm2, which means the surface area of ​​the strip.
The structure of a capacitor is made of two pieces of metal plates separated by a dielectric material. Dielectric materials are commonly known as air vacuum, ceramics, glass and others. If both ends of the metal plate was given voltage, the positive charges will accumulate on one leg (electrode) metal and at the same time the negative charges accumulated on the other end of the metal. The positive charge can not flow toward the negative pole and the opposite end of the negative charge can not go to the end of the positive pole, being separated by a dielectric material that is non-conductive. Electric charge is stored for no conduction at the ends of the legs. In the wild, these capacitors phenomenon occurs when the accumulation of positive charges and negative in the cloud.

1.1. Capacitance
Capacitance is defined as the ability of a capacitor to hold the charge of electrons. Coulombs in the 18th century calculate that 1 coulomb = 6.25 x 1018 electrons. Then Michael Faraday made postulate that a capacitor will have a capacitance of 1 farad when a voltage of 1 volt can contain as much as 1 coulombs electron charge. With the formula can be written:
Q = C V
Q = the electron charge in C (coulombs)
C = capacitance in F (farad)
V = the voltage in V (volts)
In practice the manufacture of capacitors, capacitance is calculated by knowing the area of ​​the metal plate (A), distance (t) between the two metal plates (dielectric thickness) and constant (k) dielectric materials. With the formula can be written as follows:
C = (8.85 x 10-12) (k A / t)
Here is a sample table constants (k) of some dielectric materials is simplified.

For practical electronic circuits, unit farad is a very large one. Generally capacitors on the market has units: μF, nF and pF.
1 Farad = 1,000,000 μF (micro Farad)
1 μF = 1,000,000 pF (pico Farad)
1 μF = 1.000 nF (nano Farad)
1 nF = 1000 pF (pico Farad)
1 pF = 1.000 μμF (micro-micro-Farad)
1 μF = 10-6 F
1 nF = 10-9 F
1 pF = 10-12 F
Conversion unit for ease of reading is important to know the amount of a capacitor. 0.047μF example can also be read as 47nF, or another example of the same 0.1nF 100pF.
Identified condenser has two legs and two poles is positive and negative and has a liquid electrolyte and usually tubular.

While most of the other types of rated capacity is lower, does not have a positive or negative pole on her feet, mostly in the form of flat round brown, red, green and other such tablets or buttons often called capacitors (capacitor).

2.2 The nature and kind of capacitor
Based on usefulness condenser is divided into:
1. Fixed capacitors (rated capacity can not be changed)
2. Electrolytic Capacitor (Condenser electrolit = Elco)
3. Variable capacitor (rated capacity can be changed)
In a large capacitor, the capacitance value is generally written by the sheer numbers. Complete with a maximum voltage value and polarity. For example, the elco capacitor capacitance was clearly written by 100μF25v which means the capacitor / capacitor has a capacitance of 100 μF value by the maximum allowable working voltage of 25 volts.
Capacitors are small physical size is usually only read 2 (two) or 3 (three) numbers only. If there are only two numbers, unit is pF (pico farads). For example, a capacitor that reads two numbers 47, the capacitor capacitance is 47 pF. If there are 3 digits, the first and second shows the nominal value, while the 3rd digit is the multiplier. Multiplying factor according to the nominal rate, respectively 1 = 10, 2 = 100, 3 = 1000, 4 = 10000, 5 = 100000, and so on.
Example:

For polyester capacitors capacitance value can be known by the color as in the resistor.

Example:

As with other components, there is a large nominal capacitance tolerance. In Table 2.3 are shown the value of tolerance with codes specific numbers or letters. In the table the user can easily determine tolerance capacitors are usually listed accompany nominal capacitor value. For example, if a written 104 X7R, then the capacitance is 100nF with a tolerance of + / -15%. Please also note that once the recommended working temperature is between-55Co to +125 Co.


From the above it can be known that the addition capacitance capacitor characteristics is equally important that the working voltage and operating temperature. The working voltage is the maximum allowable voltage that the capacitor can still work well. For example 10uF25V capacitor, the voltage that can be given should not exceed 25 volts dc. Generally, polar capacitors work on DC voltage and non-polar capacitor works on AC voltage. While working temperature limit is the temperature at which the capacitor can still work optimally. For example, if the written X7R capacitor, the capacitor has a recommended operating temperature between-55Co to +125 Co. Usually these characteristics specifications presented by the manufacturer in the datasheet.
2.3. The series capacitor
The series capacitor in series will result in less total capacitance value. Below is an example of capacitors arranged in series.

In a series of capacitors arranged in series applies the formula:

The series capacitors in parallel will result in the greater capacitance value replacement. Below is an example of capacitors arranged in parallel.

In parallel capacitor circuit applies the formula:

2.4. Function Capacitors
The function uses a capacitor in a circuit:
1. As the coupling between one circuit to another circuit (the PS = Power Supply)
2. As a filter in series PS
3. As the frequency generator circuit antenna
4. To save power the neon lights
5. Eliminating bounce (stepping fire) when installed on a switch
2.5. Type Capacitors
The capacitor consists of several types, depending on the dielectric material. For more simple can be divided into 3 parts, namely electrostatic capacitors, electrolytic and electrochemical.
• Electrostatic Capacitor
Electrostatic capacitors are the capacitors are made with a dielectric material of ceramic, film and mica. Ceramic and mica is a popular material and cheap to make small capacitance capacitors. Quantities available from pF to several μF, usually for a series of applications relating to high frequency. Including the dielectric films are raw materials such as polyester (polyethylene terephthalate, also known as Mylar), polystyrene, Polyprophylene, polycarbonate, metalized paper and more.
Mylar, MSM, MKT are some examples of the trademark name for a capacitor with a dielectric material film. Generally this group of capacitors are non-polar.
• Electrolytic Capacitors
Electrolytic capacitor group consisting of capacitors dielectric materials are metal-oxide layer. Generally capacitor including this group is polar capacitor with the + and - in the body. Why are these capacitors can have a polarity, is due to the manufacturing process uses electrolysis to form the positive pole and the negative pole anode cathode.
It has long been known for some metals such as tantalum, aluminum, magnesium, titanium, niobium, zirconium and zinc (zinc) surface can be oxidized to form metal-oxide layer (oxide film). Oxidation layer is formed through the process of electrolysis, as in the process of gold plating. Metal electrodes immersed in an electrolyte solution (sodium borate) and given a positive voltage (anode) and the solution given electrolit negative voltage (cathode). Oxygen in electrolyte solution apart and oxidize the surface of the metal plate. For example, if you use aluminum, it will form a layer of aluminum oxide (Al2O3) on the surface.

Thus successive metal plate (anode), layer-metal-oxide and the electrolyte (cathode) form a capacitor. In this case the metal-oxide layer as a dielectric. From the formula (2) the unknown capacitance is inversely proportional to the dielectric thickness. Metal-oxide layer is very thin, and thus can be made large enough capacitance capacitors.
Due to economical and practical reasons, it is generally a lot of metal materials used are aluminum and tantalum. Most materials are plentiful and cheap aluminum. To get the surface area, the material is typically rolled aluminum plate radial. So in a way that can be obtained large capacitance capacitors. For example 100uF, 470uF, 4700uF and others, which is also called a capacitor elco.
Electrolyte materials in liquid tantalum capacitors there but there are also solid. Called solid electrolyte, but are not really the solution electrolit its negative electrode, but other materials are manganese-dioxide. Thus this type of capacitors can have a large capacitance, but becoming more slender and petite. In addition, because all the solid, then their work time (lifetime) to be more durable. This type of capacitor has a leakage current is very small so it is understandable why Tantalum capacitors become relatively expensive.
• Electrochemical Capacitors
One other type of capacitors are electrochemical capacitors. Including this type of capacitors and batteries is the battery. In fact, battery and capacitor batteries are very good, because it has a large capacitance and leakage current (leakage current) is very small. This type of capacitor types are also still in development for a large capacitance, but small and light, for applications such electric cars and mobile phones
Capacitors are electronic components that can store electrical charge. The structure of a capacitor is made of two pieces of metal plates separated by a dielectric material. Dielectric materials are commonly known as air vacuum, ceramics, glass and others. If both ends of the metal plate was given voltage, the positive charges will accumulate on one leg (electrode) metal and at the same time the negative charges accumulated on the other end of the metal. The positive charge can not flow toward the negative pole and the opposite end of the negative charge can not go to the end of the positive pole, being separated by a dielectric material that is non-conductive. Electrical charge is "stored" as long as no conduction at the ends of the legs. In the wild, these capacitors phenomenon occurs when the accumulation of positive charges and negative in the cloud
Rectifier circuit with Filter Capacitors
The average rectifier output is DC voltage with ripple (ripple). To change this ripple to a fixed DC voltage, it takes a strainer (filter) using a capacitor as shown in figure 6

Figure 6. The hand with filters C
The process of charging and discharging currents (charging and discharging) the capacitor circuit, relies heavily on the prices of Resistors and Capacitors. Voltage at kapasistor when the charging process is as follows:

while the flow equations for the disposal process is as follows:

where konstantat time decay, commonly known as the time constant t, ie: t = RC
Role Capacitors in Electrical Energy Usage

Nuclear Batteries: Sources Unidirectional Flow Before Developed
Modern life one character is a large consumption of electrical energy. The amount of electrical energy or load that is used is determined by the reactance (R), inductance (L) and capasitansi (C). The amount of electrical energy consumption was due to numerous and diverse equipment (load) of electricity used. While commonly used electrical load is inductive and capacitive. Where the load is inductive (positive) reactive power required as the rectifier transformers, induction motors (AC) and fluorescent lamp, while the capacitive load (negative) issue of reactive power. Reactive power is power that is useless and so can not be converted into energy but it is necessary for the transmission of electrical energy to the load. So that led to a waste of electrical energy is the amount of equipment that is inductive. Means of using electrical energy turns customers not only burdened by the active power (kW), but also the reactive power (KVAR). The sum of the two forces that will produce real power is the power supplied by PLN. If a value is magnified power that is usually done by industry customers the power loss becomes big is the active power (kW) and voltages up to the consumer is reduced. Thus, the industry's production will decline this certainly should not be going for it from the power supply plus PLN should mean increased costs. Because the power is P = VI, then by increasing the amount of power means a decline in prices and the rising prices of V I. Thus, active power, reactive power and apparent power is an entity that would be described as a right-angled triangle in Figure 1.
From Figure 1 it is obtained that the ratio of active power (kW) to apparent power (kVA) can be defined as the power factor (pf) or cos r.
cos r = pf = P (kW) / S (kVA) ........ (1) P (kW) = S (kVA). cos r ................ (2)
As we know that the price cos r is from 0 s / d 1. Means the best conditions, namely when the price P (kW) maximum [P (kW) = S (kVA)] or the price cos r = 1 and is also called the cos r the best. But in reality the price cos r determined by PLN as the party of power supply is at 0.8. So for the price cos r <0.8 means pf say ugly. If the customer pf bad (low) then the capacity of active power (kW) that can be used customer will be reduced. Capacity will continue to decline along with the decline pf electrical system customers. By decreasing pf it will display some of the problems as follows: a. Enlarged kWH power usage due to losses. b. The growing use of electrical power kVAR. c. Power quality to be low because of the voltage drop. Theoretically the system with a low pf course will cause the current required from a major supplier. This will lead to a total loss of power (reactive power) and voltage drop becomes large. Thus, the penalty shall be paid sebabpemakaian increased reactive power to be great. Excess fines or fees imposed if the amount of reactive power usage in a month tercata kVARH which is higher than 0.62 kWH amount in question so that pf an average of less than 0.85. While the excessive use of kVARH in dollars using the following formula: [B - 0.62 (A1 + A2)] Hk Where: B = k VARH use kWH usage WPB A1 = A2 = kWH usage LWBP Hk = price overuse kVARH To increase prices r cos (pf) is low easy thing to do is to reduce the angle so that it becomes r1 r means r> r1. Moderate to minimize the angle r is the possible is to reduce component reactive power (KVAR). Means that there are components of reactive power is inductive to be reduced and that the reduction can be done by adding a source of reactive power in the form of capacitor.
The process of reduction is possible because both the load (inductor and capacitor) opposite direction as a result of reactive power to be small. When reactive power to active power remains small while the price of a big result pf apparent power (kVA) to be small so that the electricity bill is reduced. Meanwhile, another advantage with decreasing reactive power is:
• Reduced power losses in the system.
• An increase in voltage as the power increases.
Capacitors Work Process
Capacitors to be used to enlarge pf in parallel with the load circuit. When the series was rated voltage the electrons will flow into the capacitor. At the time of the capacitor filled with the electron charge voltage will change. Then out of the electrons will flow into the capacitor and the circuit thus the need saaat that generate reactive power capacitors. When the voltage is changed it back to normal (fixed), the capacitor will keep returning electrons. By the time capacitor emit electrons (Ic) means the same treaktif power supply capacitors to the load. Faucets load is inductive (+) while the reactive power is the capacitor (-) as a result of reactive power tends to be small.
Power loss before replacing capacitors:
Active power losses ............. = I2 R Watt (5)
Reactive power loss = I2 x VAR ......... (6)
Power loss after capacitor installed:
Active power loss = (I2 - IC2) R Watt ... (7)
Reactive power loss = (I2 - IC2) x VAR (8)
Installation of Capacitors
Capacitors to be used to minimize or correct placement pf there are two ways:
1. Centralized capacitors placed on:
a. Primary and secondary side of the transformer
b. At the central bus controller
2. How limited capacitors placed
a. Small Feeder
b. At the branch circuit
c. Jump on the load
Treatment Capacitors
Capacitors are used to improve the pf so durable would have to be treated on a regular basis. In the nursing care must be taken in damp areas that are not protected from dust and dirt. Before conducting the examination confirm that the capacitor is not connected anymore to the source. Then, because it still contains the capacitor charge means that there is no current / voltage, the capacitor is shorted should be linked so that the load is lost. The type of inspection to be performed include:
• Examination of leakage
• Checking cables and buffer capacitor
• Examination of insulator

The material is also a good source of silica, which can help reduce damage to the hair, and zinc is an essential nutrient for the hair. Try to eat a variety of grains (choose as natural as possible) to get your hair healthy, strong and shiny.

Beauty Problems: Dark circles under eyes
What to eat: Spinach
There are many causes of dark circles under the eyes, such as heredity, fatigue and anemia. But one of the causes of dark circles is due to poor blood circulation. To address these causes and reduces shadows under the eyes, try to meet the intake of vitamin K and C, which can help to improve blood circulation and strengthens capillary walls. Green vegetables such as spinach are good sources of nutrients.
Beauty Problems: Dry skin
What to eat: Nuts and seeds
Nuts and seeds are good sources of vitamin E, which can help the skin retain natural moisture level and keep it soft and hydrated. Choose flaxseed or walnuts to provide maximum benefits to the skin, because it is rich in Omega-3 fatty acids can help prevent dry skin.
Beauty Problems: Yellow Teeth
What to eat: Fruits and vegetables
Some of the most important steps to get perfect white teeth is to maintain the standard of oral hygiene (brushing, flossing and regular visits to the dentist) and avoiding cigarettes and food and beverages that can cause yellow teeth. However, after eating fruits and vegetables such as apples, celery and carrots can also help to whiten teeth. The texture of these foods can help clean your teeth after eating, eliminating bacteria and lift stains from your teeth.

basic lighting

this time I will post about the basics of lighting that I learned at school yesterday
BASIC - BASIC PROCEDURES FOR LIGHT -->

Lighting is an essential part of a production program televise.Tanpa the right lighting, the camera can produce images with clear and accurate

Lighting is also a creative part in a television production, as a result of the image can be captured by the camera according to the particular mood of the lighting work is fully defined. Therefore the above, the lighting is part of an art and a science.
The light source is distinguished by:

1. The light comes from nature, such as sunlight (natural light / daylight)
2. The light that is created or sourced from the light, the fire (an artificial light / tangten)

    The light source itself has the characteristics of light source and light intensity varies. We ignore this problem, we try to treat a system that is applicable to the work kamera.Seperti basic lighting theory.
    In every shot is influenced by the existing lighting conditions, whatever the conditions but results have also followed the lighting conditions.
    But to get the maximum results then we can follow the basic theory lighting effect, walaupunpada practice we can develop our creations as you wish, and the results will be achieved.

Lighting have 6 (six) of important basic lighting, namely:

1. Illuminating,

Which illuminates the object and subject-related needs
  electronic camera work system called light or light base foundation.

2. Creating a 3-D (three-dimensional) perspective.

Because the screen is a 2-D material (two-dimensional), then the depth
be generated by processing camera angles, blocking the camera, set
design, and the use of light-related tat texture, shape
(certain forms), form (shape).

3. Guiding the audience's attention

The light mengharahkan audience attention to important elements
of a scine.
-->
4. Create the mood of a adengan (essential mood).

As it was dark for a dramatic mystery condition, bright atmosphere in
conditions of happiness or joy.

5. Explaining time,

That morning - redness, during the day - bright / sunny, late afternoon / evening - Reddish violet.

6. Mengkotribusikan aesthetic aspects in pengkomposisian,

For example, someone walked out of the shadows passing under the lights
light then headed to the dark again

TYPES enthalpy change

Types of Enthalpy Changes
• The enthalpy change measured at 25 ° C and a pressure of 1 atm (standard state) is called the standard enthalpy change (represented by the sign of DHO or DH298).
• The enthalpy change that does not refer to the condition expressed by the symbol DH measurement alone.
• molar enthalpy = enthalpy change per mole of a substance (kJ / mol).
• The enthalpy change, include:

1. a. Standard enthalpy change of formation (DHF o) = heat of formation
Is the enthalpy change that occurs in the formation of one mole of a compound from its elements at standard temperature and pressure (25 ° C, 1 atm). Enthalpy can be released or absorbed. Its units are kJ / mol.
Standard form of an element is the most stable form of the element in the standard state (298 K, 1 atm).
If the change in enthalpy of formation was not measured at the standard state is denoted by DHF

Note:
• DHF free element is zero
• In the enthalpy of formation, the amount of substance produced is 1 mol.
• Formed from elements in standard form.

1. b. Standard enthalpy change of decomposition (DHD o)
Is the enthalpy change that occurs in the decomposition of 1 mole of a compound into its constituent elements in their default state.
If the measurements are not performed at the standard state, denoted by the DHD. Unit = kJ / mol.
Standard enthalpy change of decomposition is the reverse of the standard enthalpy change of formation, its value would be opposite in sign.
According to the Marquis de Laplace, "the amount of heat released in the formation of compound constituent elements = amount of heat needed to decomposition of the compound into its constituent elements. "This statement is called the Law of Laplace.

Example:
Given DHF o H2O (l) = -286 kJ / mol, the enthalpy of decomposition of H2O (l) into hydrogen gas and oxygen gas is +286 kJ / mol.

1. c. The standard enthalpy change of combustion (DHC o)
Is the enthalpy change that occurs in the burning of one mole of a substance completely on the state standards.
If the measurements are not performed at the standard state, it is denoted by the DHC. Unit = kJ / mol.

1. d. The standard enthalpy change of neutralization (DHN o)

Is the enthalpy change that occurs in 1 mole of acid neutralization by alkali or alkaline by 1 mole of acid in the standard state.
If the measurements are not performed at the standard state, then denoted by DHN. Unit = kJ / mol.
Example:
DHN reaction = -200 kJ
DHN NaOH = -200 kJ / 2 mol = -100 kJ / mol
DHN H2SO4 = -200 kJ / 1 mol = -200 kJ / mol

1. e. Evaporation enthalpy changes Standards (DHovap)
Is the enthalpy change that occurs in the evaporation of one mole of a substance in the liquid phase to the gas phase at standard conditions.
If the measurements are not performed at the standard state, then denoted by DHvap. Unit = kJ / mol.


1. f. Standard enthalpy change of fusion (DHofus)
Is the enthalpy change that occurs in the melting / smelting 1 mole of a substance in the solid phase a substance in the liquid phase at standard conditions.
If the measurements are not performed at the standard state, then denoted by DHfus. Unit = kJ / mol.

1. g. Standard Sublimation enthalpy changes (DHosub)
Is the enthalpy change that occurs in sublimation 1 mole of a substance in the solid phase a substance in the gas phase at standard conditions.
If the measurements are not performed at the standard state, then denoted by DHsub. Unit = kJ / mol.

1. h. Standard Dissolution enthalpy changes (DHosol)
Is the enthalpy change that occurs when one mole of a substance dissolves in a solvent (usually water) at standard conditions.
If the measurements are not performed at the standard state, then denoted by DHsol. Unit = kJ / mol.
