A parallel plate capacitor is charged and then isolated. The effect of increasing the plate separation on charge, potential and capacitance respectively are

A

Constant, decreases, decreases

B

Increases, decreases, decreases

C

Constant, decreases, increases

D

Constat, increases, decreases

Text Solution

Verified by Experts

The correct Answer is:
D
As the capacitor is isolated after charging, charge on it remains constant. Plate separation increases d, decreases `C=epsilon_(0)A//d` and hence increases potential `V=Q//C`.
