The capacitance is a ratio b/w electric charge and potential difference.
This capacitance is measured with a multimeter. This multimeter is a combination of different measuring meters. This multimeter estimates the electric charge in coulombs, and potential difference, and calculates the charge to potential difference ratio to give capacitance value keeping all the other parameters in check.
Farad is the unit of capacitance. It is named after Michael Faraday.
The farad measures how much electric charge is accumulated on the capacitor.
1 farad is the capacitance of a capacitor that has charge of 1 coulomb when applied voltage drop of 1 volt.
1F = 1C / 1V
| name | symbol | conversion | example |
|---|---|---|---|
| picofarad | pF | 1pF=10-12F | C=10pF |
| nanofarad | nF | 1nF=10-9F | C=10nF |
| microfarad | μF | 1μF=10-6F | C=10μF |
| millifarad | mF | 1mF=10-3F | C=10mF |
| farad | F | C=10F | |
| kilofarad | kF | 1kF=103F | C=10kF |
| megafarad | MF | 1MF=106F | C=10MF |
The capacitance C in farad (F) is equal to the capacitance C in picofarad (pF) times 10-12:
C(F) = C(pF) × 10-12
Example - convert 30pF to farad:
C(F) = 30 pF × 10-12 = 30×10-12 F
The capacitance C in farad (F) is equal to the capacitance C in nanofarad (nF) times 10-9:
C(F) = C(nF) × 10-9
Example - convert 5nF to farad:
C(F) = 5 nF × 10-9 = 5×10-9 F
The capacitance C in farad (F) is equal to the capacitance C in microfarad (μF) times 10-6:
C(F) = C(μF) × 10-6
Example - convert 30μF to farad:
C(F) = 30 μF × 10-6 = 30×10-6 F = 0.00003 F
The farad (symbolized F) is the standard unit for capacitance within the International System of Units (SI). Reducing it to the basic SI units one farad represents equivalent to 1 second of the 4th power ampree squared for every kilogram of weight in squared (s4 * A2* kg-1 * m-2).
