Question

Can a transformer work on dc? Justify your answer.

Answer 1

Answer:

Yes, the transformer can work on DC when paired with a rectifier.

Explanation:

Normally, a transformer cannot work on direct current because the current is always constant and there is no relative motion between the coil and the core. This relative motion is very important for a transformer to work as it induces the EMF in the secondary coil of the transformer.

In order to to get the transformer working, a rectifier needs to be used along with the DC transformer otherwise the Transformer won't work.
