Question

Accepted Answer

A transformer is a static machine used for stepping up or stepping down voltage.

Transformers are used to transfer electrical energy from one circuit to another through electromagnetic induction.
They consist of two coils of wire, the primary and secondary, wrapped around a magnetic core.
The primary coil is connected to the input voltage source, while the secondary coil is connected to the output load.
Transformers can increase or decrease voltage depending on the number of turns in the primary and secondary coils.
They are commonly used in power distribution systems, electronic devices, and appliances.
Examples include power transformers used in electrical substations, audio transformers in amplifiers, and voltage regulators in electronic devices.
