Why transformer does not work on dc?

Question

Accepted Answer

Transformers do not work on DC because they rely on the principle of electromagnetic induction.

Transformers operate based on the principle of electromagnetic induction, which requires a changing magnetic field.
In AC (alternating current) systems, the current continuously changes direction, creating a changing magnetic field.
The changing magnetic field induces a voltage in the secondary winding of the transformer, allowing for voltage transformation.
In DC (direct current) systems, the current flows in one direction, resulting in a constant magnetic field.
Since there is no changing magnetic field, there is no induction of voltage in the secondary winding of the transformer.
Therefore, transformers are designed to work specifically with AC systems.
