If mica of dielectric constant K s placed between the plates. What are its advantages? Explain action of mica in the case.

Assertion : When a dielectric slab of dielectric constant K is introduced between the plates after disconnecting the battery, energy stored in the capacitor decreases. Reason : Potential difference between two plates decrease by a factor K ad charge remains the same, so energy decreases.

A dielectric slab is placed between the plates of a parallel plate capacitor. Its capacitance.

Explain what would, happen to the potential difference between the plates if in a capacitor of capacitance 1.771 xx 10^-11 F , 3 mm thick sheet (of dielectric constant = 6) is inserted between the plates:- When the supply voltage is disconnected.
