Transformers

A transformer is a device for transferring alternating current energy from one circuit to another, by electromagnetic induction. In its simplest form, a transformer consists of two windings on a laminated iron core. The winding connected to the source voltage is called the primary winding and the winding connected to the load is called the secondary winding. Transformers are used in applications where it is required to increase or decrease voltage, or to provide electrical isolation between the source and the load.
