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

A

n =0

B

`n lt n, `

C

`n = r _(s)`

D

`n gt n _(r)`

Text Solution

Verified by Experts

`If n gt n _(r) omega L gt (1)/( omega c ) X _(L) gt X _(C) `
So, current lags behind voltage
