Why can a DC motor run on a DC supply, but a transformer will be damaged if connected to the same DC supply? Answer : The reason lies in their fundamentally different operating principles: **Back EMF** in a DC motor versus **Mutual Induction** in a transformer. **1. The DC Motor: Operation via Back EMF** A ... from an AC supply and has no internal mechanism to limit a DC current, leading to its rapid destruction....
