A resistor `R`, an inductor `L` and a capacitor `C` are connected in series to a source of frequency `n`. If the resonant frequency is `n_(r)`, then the current lags behind voltage when

A

`n=0`

B

`n lt n_(r)`

C

`n=n_(r)`

D

`n gt n_(r)`

Text Solution

Verified by Experts

Below resonant frequency the current leads the applied emf, at resonance it is in phase with applied emf and above resonance frequency it lags the applied emf.
