To solve the problem, we need to understand the functioning of a transformer and the implications of connecting it to a DC supply. ### Step-by-Step Solution: 1. **Understanding the Transformer**: A transformer operates on the principle of electromagnetic induction and is designed to work with alternating current (AC). It consists of two coils: the primary coil and the secondary coil. 2. **Given Information**: - Turns in the primary coil (N1) = 50 ...
