Assertion : In series L-C-R, AC circuit,...

Assertion : In series `L-C-R, AC` circuit, current and voltage are in same phase at resonance.
Reason : In series `L-C-R, AC` circuit, resonant frequency does not depend on the value of resistance. Hence, current at resonance does not depend on resistance.

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:
C
At resonasnce `X_L=X_C`
`implies Z=R`
Hence, `I=V/Z=V/R`
So, current at resonance depends on `R`.
