To solve the problem, we need to calculate the induced electromotive force (emf) when the current in the primary coil of a transformer changes. We will use the formula for induced emf based on mutual inductance. ### Step-by-Step Solution: 1. **Identify Given Values:** - Coefficient of mutual inductance (M) = 5 H (Henries) - Initial current in primary (I_initial) = 3 A - Final current in primary (I_final) = 0 A ...
