  1. Question 1

    Q1. The voltage across a resistor, inductor, and capacitor in series are 10 V, 15 V, and 10 V respectively. The voltage applied is

    • A) 35 V
    • B) √(10² + (15-10)²) V
    • C) 10 V
    • D) 15 V

    Answer: √(10² + (15-10)²) V

    Explanation: V = √(VR² + (VL - VC)²) = √(10² + (15-10)²) = √(100 + 25) V.
