A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit,or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core,which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction,discovered in 1831,describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil.
