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