In LCR circuit, the impedance Z is given by `Z=sqrt(R^2+(omegaL-1/(omegaC))^2)`
The current in LCR circuit will be maximum if frequency is:

A

`Z=R`

B

`ZltR`

C

`ZgtR`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Z = R
Explanation: At resonance `omegaL=1/(omegaC)`
We get minimum value Z = R
If Z is minimum, the current will be higher
