  1. Question 1

    Q1. In an LCR circuit, the voltage across the resistor is 100 V, across the inductor is 200 V, and across the capacitor is 200 V. The supply voltage is

    • A) 100 V
    • B) 200 V
    • C) 300 V
    • D) 100√2 V

    Answer: 100 V

    Explanation: At resonance, Vl = Vc, so V = Vr = 100 V, as Vl and Vc cancel out.
