engineering physics MCQ #181

  1. Question 1

    Q1. In a series LCR circuit, the voltage across the capacitor is 100 V, and the voltage across the inductor is 100 V. The voltage across the resistor is

    • A) 0 V
    • B) 100 V
    • C) 141.42 V
    • D) 200 V

    Answer: 141.42 V

    Explanation: At resonance, V_L = V_C, so V_R = √(V² - (V_L - V_C)²) = V, but since V_L = V_C, we directly use V_R = V.
