Question

what is capacitance? ​

Answer 1

Capacitance is the ratio of the change in an electric charge in a system to the corresponding change in its electric potential. There are two closely related notions of capacitance: self capacitance and mutual capacitance. Any object that can be electrically charged exhibits self capacitance.

Answer 2

Capacitance is the ratio of the change in an electric charge in a system to the corresponding change in its electric potential.
