  1. Question 1

    Q1. In a series 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: VL and VC are equal and opposite, so net voltage is V = √(VR² + (VL - VC)²) = VR = 100 V.
