_________ the resonant frequency, the current in the capacitor leads the voltage in a series RLC circuit.(a) Above(b) Below(c) Equal to(d) Depends on the circuitI had been asked this question in quiz.My enquiry is from The Current in a Series RLC Circuit topic in section Resonance in AC Circuits of Basic Electrical Engineering

Answer»

Correct option is (b) Below

For explanation I would say: The current in the capacitor leads the VOLTAGE in a series RLC circuit if circuit is capacitive DOMINANT i.e.i.e. if XL < XC

ωL < 1/ωC=> ω < 1/√LC=> ω < ω0.

So, the current in the capacitor leads the voltage in a series RLC circuit below the resonant frequency.
