Why transformers only works with AC?

To understand why transformer only works works with ac we need to understand it's principle. The transformer is a static device, that contains of one or more windings that are coupled magnetically and separated electrically with a magnetic core. read more

Why Transformers Only Works With Alternating Current The transformer is a static device that changes electrical energy from one circuit to another circuit with the help of mutual induction (without any connection) between two windings namely primary winding and secondary winding. read more

Transformers only work on ac supply because it principle is mutual induction. DC supply has constant magnitude whereas AC has alternating magnitude. so we can step up or step down current/voltage in transformer in ac only. read more
