The current lags the supply voltage in a series RLC circuit has its frequency _________ the resonant frequency.(a) Above(b) Below(c) Equal to(d) Cannot be determined

Answer» The correct choice is (a) Above

For explanation I would say: Current is lagging the voltage indicates inductor dominating circuit.                                                                          XC < XL => 1/(ωC) < ωL  => ω > 1/√LC

So, frequency more than resonant frequency.
