Assertion : Resonance is exhibited by a circuit only if both L and C are present in the circuit.
Reason : Only then the voltage across L and C cancel each other, both being out of phase.

A

If both assertion ans reason are true ans reaason 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 istrue but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
The resonance phenomenon is exhibited by a circuit only if both L and C are present in the circuit. Only then the voltages across L and C cancel each other since both being out of phase and current amplitude is `V_(m//R)`, the total source voltage appearing across R. This means that we cannot have resonance in a RL or RC circuit.
