Background
A transformer is a device that changes an alternating voltage using the principle of electromagnetic induction. In electrical equipment and wireless circuits, transformers are often used to step up and down voltage, match impedance, safety isolation, etc. In a generator, an electric potential is induced in a coil, whether the coil is moved through a magnetic field or the magnetic field is moved through a stationary coil, in both cases the value of the flux is constant, but the amount of flux linked to the coil varies, which is the principle of mutual induction. A transformer is a device for transforming voltage, current and impedance by using mutual electromagnetic induction. In its most basic form, a transformer comprises two sets of windings wound with conductive wire and inductively coupled to each other. When an alternating current flows through one of the coils, an alternating voltage having the same frequency is induced in the other coil, and the magnitude of the induced voltage depends on the degree of coupling and magnetic linkage between the two coils.
