Assertion: At frequency greater than resonance frequency circuit is inductive in nature.
Reason: `X_(L) propto omega`

A

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

B

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

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
At `omega=omega_(r)`, `X_(L)=X_(C)`
At `omegagtomega_(r)`, `X_(L)gtX_(C)` as,
`X_(L) propto omega` and `X_(L) propto 1/omega`
