A transformer is an electrical device that is used to transfer electrical energy from one circuit to another, using electromagnetic induction. It consists of two coils of wire, called the primary and secondary windings, that are wound around a common magnetic core. When an AC voltage is applied to the primary winding, it creates a changing magnetic field that induces a voltage in the secondary winding. By varying the number of turns in the primary and secondary windings, transformers can be used to step up or step down voltage levels in a circuit.
10. What is a diode, and how is it used in an electrical circuit?
