  1. Question 1

    Q1. In a series LCR circuit, the voltage across the resistor is 10 V, across the inductor is 20 V, and across the capacitor is 20 V. The supply voltage is

    • A) 10 V
    • B) 20 V
    • C) 30 V
    • D) 10√2 V

    Answer: 10 V

    Explanation: At resonance, V_L = V_C, so V = V_R = 10 V
