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....

How is the efficiency of a transformer calculated?
Answer : The efficiency of a transformer is calculated by comparing the output power to the input power. It shows how effectively the transformer converts electrical energy from the primary side (input) to ... in real transformers, there are always some losses, making the efficiency slightly less than 100%....
