Answer:
Transformers work only on AC current and not on DC because a change in current can’t be generated by DC and there isn’t a magnetic field to cause a voltage across the secondary component.
If a transformer is connected to a DC supply, the primary of the transformer will act as a short circuit path to the additional DC current, which may blow the overall transformer.
Alternating Current (AC) changes its magnitude and direction in cyclic intervals.
This produces a continually changing magnetic field within the transformer which induces an electric current in the second coil.
