The current in the capacitor leads the voltage in a series RLC circuit ___________ resonant frequency.(a) Above(b) Below(c) Equal to(d) Depends on the circuitThe question was asked in quiz.The question is from Voltages in a Series RLC Circuit topic in division Resonance in AC Circuits of Basic Electrical Engineering

Answer»

Correct choice is (B) Below

The explanation: The current in the capacitor leads the voltage in a series RLC CIRCUIT if circuit is capacitive dominant 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.
