    A transformer is an electrical device which, by the principles of electromagnetic induction, transfers electrical energy from one electric circuit to another, without changing the frequency. The energy transfer usually takes place with a change of voltage and current.

    The major function of a transformer is to step up or step down the voltage in an Alternate Current (AC) circuit.
