The capacitance of a capacitor



The capacitance of a capacitor is defined as the amount of charge required to create a unit p.d. between its plates.

Suppose we give Q coulomb of charge to one of the two plates of a capacitor and if a p.d. of V volts is established between the two, then it's capacitance is


Q Charge

C = ----- = --------------------

V Potential Difference
