In a parallel–plate capacitor, the region between the plates is filled by a dielectric also. The capacitor is connected to a cell and the slab is taken out.
- Some charge is drawn from the cell
- Some charge is returned to the cell
- The potential difference across the capacitor is
reduced - No work is done by an external agent in taking the
slab out
Answer
(B) Some charge is returned to the cell
