Problem

For a series

RLC

circuit operated at a frequency

f

such that

f < f_0

(where

f_0

is its resonant frequency), which statement is correct? (a)

X_L > X_C

and current leads the source voltage (b)

X_L < X_C

and current lags the source voltage (c)

X_L < X_C

and current leads the source voltage (d)

X_L = X_C

and current is in phase with the source voltage
