engineering physics MCQ #1227

  1. Question 1

    Q1. Two coils have a mutual inductance of 0.01 H. If current in one coil changes at a rate of 100 A/s, induced emf in the other coil is

    • A) 0.1 V
    • B) 1 V
    • C) 10 V
    • D) 100 V

    Answer: 1 V

    Explanation: Induced emf = -M(dI/dt) = -0.01 * 100 = -1 V.
