Alternating CurrentHard

Question

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

Options

A.υ = 0
B.υ < υr
C.υ = υr
D.υ > υr

Solution

So, current lags behind voltage.
If      n > nr
ωL >
XL > XC
