Assertion: In an `AC` circuit, potential difference across the capacitor may be greater than the applied voltage.
Reason : `V_C=IX_C`, wheereas `V= IZ` and `X_C` can be greater than `Z` also.

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
`Z=sqrt(R^2+(X_C-X_L)^2)`
From this expression we can see that `X_C` may greater than `Z` also.
