Problem

Consider an air-filled charged parallel plate capacitor. How can its capacitance be increased?

a) Increase the charge on the capacitor.

b) Decrease the charge on the capacitor.

c) Increase the spacing between the plates of the capacitor.

d) Decrease the spacing between the plates of the capacitor.

e) Increase the length of the wires leading to the capacitor plates.

Solution

C=ε0Ad

The capacitance of the parallel plate capacitor is affected by the permittivity of material used, area of the plates and plate separation. The capacitance can be increased by:
