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 |
