Transformer — Wikipedia Republished // WIKI 2 transformer is a static electrical device that transfers electrical energy between two or more circuits. A varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force (emf) or "voltage" across a second coil wound around the same core. Electric power can be transferred between the two coils, without a metallic ...
