Answer the following.
A parallel plate capacitor is charged by a battery; which is then disconnected. A dielectric slab is now introduced between the two plates to occupy the space completely. State the effect on the following:
(i)[1.0]
the capacitance of the capacitor.
(ii)[1.0]
potential difference between the plates.
(iii)[1.0]
the energy stored in the capacitor.
