engineering physics MCQ #1273

  1. Question 1

    Q1. A coil of 500 turns, area 0.1 m² is rotated at 500 rpm in a field of 0.2 T. The maximum induced emf is

    • A) 104.7 V
    • B) 10.47 V
    • C) 52.35 V
    • D) 5.235 V

    Answer: 52.35 V

    Explanation: ε = NABω = 500 * 0.1 * 0.2 * (500/60) * 2π = 52.35 V.
