Which of the following is not the characteristic of resonance in an LCR series circuit?

A

`X_(L)=X_(C )`

B

`omega L=1/(omegaC)`

C

`2pifL=2pifC`

D

`f_(0)=1/(2pi) sqrt(1/(LC))`

Text Solution

Verified by Experts

The correct Answer is:
C
`2pifL=2pifC`
Explanation :At resonance , `X_(L)=X_(C)`
` :. omegaL=1/(omegaC)`
`omega^(2)=1/(LC)`
`(2pif_(0))^(2)=1/(LC)`
`f_(0)=1/(2pi) sqrt(1/(LC))`
