Unit Of Capacitance:
Whenever a battery is connected among the plates of a capacitor, it takes few times before the electrical field reaches its full intensity. The voltage builds up at a rate which depends on the capacitance. The greater the capacitance is, the slower is the rate of change of voltage in the plates.
The unit of capacitance is an expression of the ratio among the quantity of current flowing and the rate of voltage change across the plates of a capacitor. A capacitance of 1 farad, abbreviated as F, symbolizes a current flow of 1 ampere (1 A) whereas there is a potential-difference rise or reduce of 1 volt per second (1 V/s). A capacitance of 1 F also outcomes in 1 V of potential difference for an electric charge of 1 coulomb (1 C). The farad is a vast unit of capacitance. You will almost never see a capacitor with a value of 1 F. Generally employed units of capacitance are the microfarad (µF) and the picofarad (pF). A capacitance of 1πF symbolizes 0.000001 (10-6) F, and 1 pF is 0.000001 µF, or 10-12 F.
