A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to one or more circuits. A varying current in any one coil of the transformer produces a varying magnetic flux , which, in turn, induces a varying electromotive force across any other coils wound around the same core. Electrical energy can be transferred between the possibly many coils, without a metallic connection between the two circuits. Faraday's law of induction discovered in described the induced voltage effect in any coil due to changing magnetic flux encircled by the coil. Transformers are used for increasing alternating voltages at low current Step Up Transformer or decreasing the alternating voltages at high current Step Down Transformer in electric power applications, and for coupling the stages of signal processing circuits. Since the invention of the first constant-potential transformer in , transformers have become essential for the transmission , distribution , and utilization of alternating current electric power.
