  1. Question 1

    Q1. A circular coil of 100 turns, radius 0.1 m is rotated at 1000 rpm in a field of 0.01 T. The maximum induced emf is

    • A) 10.47 V
    • B) 1.047 V
    • C) 104.7 V
    • D) 0.1047 V

    Answer: 10.47 V

    Explanation: ε = NABω = 100 * π * (0.1)² * 0.01 * (1000/60) * 2π = 10.47 V, simplified.
