  1. Question 1

    Q1. Two coils have mutual inductance of 5 mH. If the primary current changes at 10 A/s, what EMF is induced in the secondary?

    • A) 0.05 V
    • B) 50 V
    • C) 0.5 V
    • D) 5 V

    Answer: 0.5 V

    Explanation: EMF = M × ΔI/Δt. Option A neglects unit conversion (mH → H).
