Question

When a dielectric slab is introduced between the plates of a charged capacitor with battery connected across the plates what will be happen to- (1)potential (2)charge (3)electric field (4) total energy

Answer 1

Answer:

When dielectric is introduced, the capacitance will increase and as the battery remains connected, so the voltage will remain constant. Hence according to Q=CV the charge will increase. Himachal Pradesh 2021 class 12 board exam are set to begin on 13th April 2021.

Explanation:

Answer 2

Answer:

Charge

The electric field between the two plates is reduced as the dielectric slab is inserted due to some charge distribution in the slab, which enables the capacitor to store more charge.

Potential:

The capacitance will rise as dielectric is added, and because the battery is still connected, the voltage will stay constant.

Total energy

The capacitance will rise as dielectric is added, and because the battery is still connected, the voltage will stay constant. Therefore, the charge will rise since "Q = CV."

Electric field:

After disconnecting the battery, the electric field between the plates of a charged condenser reduces when a dielectric material is added there.
