A capacitor between whose plates there is a dielectric with a dielectric constant e is connected to a DC source. How will the energy stored in the capacitor change if the dielectric is removed? Explain the cause of this change.

A parallel plate capacitar, of capacitance, 20 mu F , is connected to a 100 V supply. After some time, the battery is disconnected , and the space, between the plates of the capacitor is filled with a dielectric, of dielectric constant 5. Calculate the energy stored in the capacitar (i) before (ii)after dielectric has been put in between its plates.

Parallel Plate Capacitors with and without Dielectric

A capacitor of capacitance 200 mu F is connected to a 200V battery. Dielectric material of dielectric constant 2 is introduce in between the plates of the capacitor. Find change in energy stored in the process.

A capacitor has some dielectric between its plates, and the capacitor is connected to a DC source. The battery is now disconnected and then the dielectric is removed. State whether the capacitance, the energy stored in it, electric field, charge stored and the voltage will increase ro remain constant.

A parallel plate capacitor carries a harge Q. If a dielectric slab with dielectric constant K=2 is dipped between the plates, then

In a parallel-plate capacitor, the region between the plates is filled by a dielectric slab. The capacitor is connected to a cell and the slab is taken out. Then

A parallel plate capacitor is charged by a battery. After some time the battery is disconnected and a dielectric slab of dielectric constant K is inserted between the plates. How would (i) the capacitance, (ii) the electric field between the plates and (iii) the energy stored in the capacitor, be affected ? Justify your answer.
