Questions
A capacitor is charged by using a battery which is then disconnected. A dielectric slab is then slipped between the plates, which results in
detailed solution
Correct option is C
Battery in disconnected so Q will be constant. As C ∝K, so with introduction of dielectric slab capacitance will increase. Using Q = CV, V will decrease and using U=Q22C, energy will decreaseTalk to our academic expert!
