  1. Question 1

    Q1. The mutual inductance between two coils is 0.5 H. If current in one coil changes from 0 to 2 A in 1 s, induced emf in the other coil is

    • A) 0.5 V
    • B) 1 V
    • C) 2 V
    • D) 4 V

    Answer: 1 V

    Explanation: Induced emf = -M(dI/dt) = -0.5 * (2 / 1) = -1 V.
