In a parallel–plate capacitor, the region between the plates is filled by a dielectric slab. The capacitor is charged from a cell and then disconnected from it. The slab is now taken out.
- The potential difference across the capacitor is reduced
- The potential difference across the capacitor is increased
- The energy stored in the capacitor is reduced
- No work is done by an external agent in taking the slab out
Answer
(B) The potential difference across the capacitor is increased
