Define capacitance of a capacitor and its SI unit.

Explanation

Definition : The capacity of a capacitor to stor the charge is called its Capacitance.
It is the ratio of magnitude of charge on either of conductor to the magnitude of potential difference between two conductors
`i.e., C=(Q)/(V)`
`1F=(1"Coulomb")/(1"Volt")`
In other words, A Capacitor has a Capacitance of one , farad, if the potentital difference across it rises by 1 volt, when I Coulomb of charge is given to it.
The S.I. unit of capacitance is Farad.
