Assertion : When an uncharged capacitor ...

Assertion : When an uncharged capacitor is charged by a battery only `50%` of the energy supplied is stored in the capacitor.
Reason : Rest `50%` is lost.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A, B
Energy supplied by the battery is
`/_\qV=(CV)(V)=CV^2`
Energy stored in the capacitor is `1/2CV^2`
