_________ the resonant frequency, the current in the inductor lags the voltage in a series RLC circuit.

A)
Above
B)
Below
C)
Equal to
D)
Depends on the circuit

Correct Answer : Option (A) :   Above

Explanation : The current in the inductor lags the voltage in a series RLC circuit if a circuit is inductive dominant i.e. if XL > XC
ωL > 1/ωC => ω > 1/√LC => ω > ω0.
So, the current in the inductor lags the voltage in a series RLC circuit above the resonant frequency.
