Capacitor and Capacitance
Electrical capacitance of a conductorCapacitance is the constant of proportionality relating charge to the potential difference between the conductors in a capacitor.
where is the capacitance, is the charge contained and is the potential difference.
The SI Unit of capacitance is or Common unit is Farad.
Capacitance of parallel plate capacitorWe know that
putting these values in capacitance formula we get
Where, A = Area of plate, d = Distance between capacitor plates
