Why transformer works on AC rather than DC? Answer : A transformer works on **AC (Alternating Current)** rather than DC (Direct Current) because of the way it relies on changing magnetic fields to transfer energy between its coils. Here's how it works: 1 ... *. With **DC**, the magnetic field doesn't change, and the transformer can't transfer power....
