Capacitance

Definition

The capacitance is the physical measure, which defines the property of conductive bodies, to store and maintain the electrical charges and it is numerically equal to the ratio of the charge applied on the conductor to the change of potential of this conductor.

1 farad is the capacitance of a separate conductor, for which the charge of 1 coulomb increases its potential with 1 volt.
