Correct Answer : Option (B) : Damage the transformer
Explanation : As we know, a transformer works on the principle of mutual induction, where you need a dynamic magnetic field to generate an induced emf in the secondary winding. In direct current supply, the change in frequency with respect to time is null, which means the dc supply can't produce a dynamic magnetic field; hence mutual induction can't possible on direct current supply since the primary winding of the transformer has a very low value of resistance so it can't oppose the excessive flow of current; therefore, the current having high value can damage the windings.
