Transformer

High Quality Content by WIKIPEDIA articles! A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors-the transformer\'s coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer\'s core and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF), or "voltage", in the secondary winding. This effect is called inductive coupling.
