Introduction For Capacitors

Definition Capacitors
Capacitors are electronic components that can store electrical charges. The structure of a capacitor made of 2 pieces of metal plates separated by a dielectric material. Dielectric materials are commonly known as air vacuum, ceramic, 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 metal edges of one another. The positive charge can not flow toward the negative pole and the opposite end of the negative charge can not be heading back up the positive pole, because the dielectric material separated by a non-conductive. Electric charge is "stored" as long as no conduction at the ends of the legs. In the wild, this phenomenon occurs when the capacitor charge accumulation-positive and negative charges in the clouds.

Capacitors are passive electronic components that are often used in designing a system that serves to block DC current, filter, and electrical energy storage. In it 2 pieces of plate electrode facing each other and separated by an insulator. While the materials used as an insulator called a dielectric. When the capacitor voltage DC provided the electric energy stored in each electrode. During the capacitor charging, current flows. The current flow will stop when the capacitor has been full. What distinguishes each - each capacitor is a dielectric.

Value and the unit is farad capacitor and is usually abbreviated F.
The value of this unit is considered too basic, so the unit farad is reduced again to the units as follows:


microfarads (µF)               nanoFarads (nF)                        picoFarads (pF)
0.000001µF          =         0.001nF                  =               1pF
0.00001µF            =         0.01nF                    =               10pF
0.0001µF              =         0.1nF                      =               100pF
0.001µF                =         1nF                         =               1000pF
0.01µF                  =         10nF                       =               10,000pF
0.1µF                    =         100nF                     =               100,000pF
1µF                       =         1000nF                   =               1,000,000pF
10µF                     =         10,000nF                =               10,000,000pF
100µF                   =         100,000nF              =               100,000,000pF


1 F   = 1 Farad = 1,000,000 Micro Farad
1 uF = 1000 nF = 100 KpF
1 uF = 1,000,000 pico Farad


Value capacitor in addition to written with color coding as in the resistor, most written with numerical symbols like this:


0.1 Means uF 0.1
0.001 means 0.001 uF
102 means 10 x 102
pF = 100 pF = 1 KpF
203 means 20 x 103
pF = 200 PF = 20 KpF
