Assertion , A parallel plate capacitor is charged by a battery, when battery is disconnected , if the space between the plates is filled with a dieelectric, then energy stored will increase.
Reason : Due to the introduction of dielectric the capacitance will be increased.

A

Both Assertion and reason are false

B

Assertion is false and reason is true

C

Both assertion and reason are true and reason explain assertion correctly

D

Both assertion and reason are true and reason does not explain assertion correctly.

Text Solution

Verified by Experts

The correct Answer is:
D
Energy `U = Q^2/(2C)`
As battery is disconnected the charge Q remains same. Hence C increases and energy will be decreased.
