why dc power can not be used in transformer?

Answer Posted / subhrajyoti de

Transformer work on the principle of mutual induction.
If DC voltage is supplied then there will be no change in flux as a result no EMF will be induced in the secondary winding and the will be no output.

On the other hand, the primary windings will get heated up and may blow up after sometime.
