Two coils have mutual inductance of 5 mH. If the primary current changes at 10 A/s, what EMF is induced in the secondary?
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?
Answer: 0.5 V
Explanation: EMF = M × ΔI/Δt. Option A neglects unit conversion (mH → H).
