Question
A capacitor is charged by using a battery which is then disconnected. A dielectric slab is then slipped between the plates, which results in:
Answer: Option C
:
C
The charge on the plates does not change as the capacitor is disconnected from the battery. The presence of dielectric slab increases the capacitance, which decreases the potential difference. Thus, the energy stored is reduced.
