An L-C-R series A.C. circuit is tuned to resonance. The impedance of the circuit is ……

Answer»

`[R^2 +(omegaL-1/(omegaC))^2]^(1/2)`
`[R^2+(omegaL)^2+(1/(omegaC))^2]^(1/2)`
`[R^2+(1/(omegaC)-omegaL)^2]^(1/2)`
R

Solution :When resonance occur, then `omegaL=1/(omegaC)`
`|Z|=sqrt(R^2+(omegaL-1/(omegaC))^2)=R`
