A transformer is a pair of coils coupled magnetically (Fig.3.1), so that some of the magnetic flux produced by the current in the first coil links the turns of the second, and vice versa. The coupling can be improved by winding the coils on a common magnetic core (Fig.3.2), and the coils are then known as the windings of the transformer.

Example: A transformer with a 480 volt input, 240 volt output— can have the output connected to a 240 volt source and thereby become the primary or input to the transformer, then the original 480 volt primary winding will become the output or 480 volt secondary. ... It can be designed to “step up” or “step down…
