A capacitor is charged by using a battery which is then disconnected. A dielectric slab is then slipped between the plates, which results in
- A
Reduction of charge on the plates and increase of potential difference across the plates
- B
Increase in the potential difference across the plate, reduction in stored energy, but no change in the charge on the plates
- C
Decrease in the potential difference across the plates, reduction in the stored energy, but no change in the charge on the plates
- D
None of the above
