Capacitance of a Capacitor

Capacitance is the ability of an object to store electric charge and is the amount of charge stored per unit voltage on a device. It is represented by C and is calculated as:

Q is the magnitude of the charge distributed on either surface, in coulombs, and V is the potential difference between the surfaces, in volts.

The unit of capacitance is farad (F). One farad is equal to one coulomb per volt.
