Alternating CurrentMedium
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.
