$Q=CV$

$C=Q/V$

where $C$ is the capacitance, $Q$ is the charge contained and $V$ is the potential difference.

The SI Unit of capacitance is$VoltCoulomb $ or Common unit is

**Farad.**

$1VoltCoulomb =1Farad$

Physics

$Q=CV$

$C=Q/V$

where $C$ is the capacitance, $Q$ is the charge contained and $V$ is the potential difference.

The SI Unit of capacitance is$VoltCoulomb $ or Common unit is

But $Q=σA$ and $ΔV=Ed$

putting these values in capacitance formula we get

$C=dϵ_{o}A $

Where, A = Area of plate, d = Distance between capacitor plates
