  1. Question 1

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

    • A) 100√2 V
    • B) 200 V
    • C) 100 V
    • D) 141.4 V

    Answer: 100√2 V

    Explanation: V = √(VR² + VC²) = √(100² + 100²) = √(10000 + 10000) = √20000 = 100√2 V.
