The current in the capacitor ___________ the voltage in a series RLC circuit below the resonant frequency.(a) Leads(b) Lags(c) Equal to(d) Depends on the circuitI have been asked this question during an internship interview.The origin of the question is Voltages in a Series RLC Circuit topic in division Resonance in AC Circuits of Basic Electrical Engineering

Answer» CORRECT answer is (a) Leads

For explanation: ω < ω0 => ω < 1/√LC

=> ωL < 1/ωC=>XL < XCThe circuit is capacitive DOMINANT so, the current in the CAPACITOR leads the voltage in a series RLC circuit above the resonant frequency.
