A transformer is a device which step-up or step-down the level of AC current or voltage without changing the primary (i.e. input source) frequency. Transformer only works on AC and can't be operated on DC i.e. it has been designed to be operated only and only on alternating current and voltage
As mentioned before, transformers do not allow DC input to flow through. This is known as DC isolation. This is because a change in current cannot be generated by DC; meaning that there is no changing magnetic field to induce a voltage across the secondary component.
Explanation:
Transformer fails to transfer power from primary to secondary. Thus DC supply is not used for transformer. In DC supply we cant get the alternating flux to be linked to the secondary. As the emf induced in secondary is directly proportional to the variation of flux in secondary.

A transformer is not designed to convert AC to DC or DC to AC. The transformer can step-up or step -down current. A transformer that increases the voltage from the primary to secondary is called a step-up transformer.
