Transformer - Wikipedia transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. . Electrical energy can be transferred between ...
