The transformer consists of iron core and coil with two or more windings, the winding connected to power source is called primary winding and the other windings are called secondary winding. In a generator, either the coil movement through a magnetic field or the movement of a magnetic field through a fixed coil, a potential is induced in the coil, both of which are the same in value but vary in the amount of flux that intersects the coil, which is the principle of mutual induction. A transformer is a device that transforms voltage, current and impedance using the electromagnetic mutual inductance effect.
