Transformers, and generator alternator working principle

Question

Accepted Answer

Transformers and generator alternators are devices that convert electrical energy from one form to another.

Transformers work on the principle of electromagnetic induction, where a changing current in one coil induces a voltage in another coil.
They are used to step up or step down voltage levels in electrical power transmission and distribution systems.
Generator alternators, also known as synchronous generators, convert mechanical energy into electrical energy through the principle of electromagnetic induction.
They consist of a rotor and a stator, where the rotor is driven by a mechanical source such as a turbine or an engine, and the stator contains the windings that generate the electrical output.
Generator alternators are commonly used in power plants, wind turbines, and other applications where electrical power needs to be generated.
