Tell me about transformers

Question

Accepted Answer

Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.

Transformers are used to increase or decrease voltage levels in electrical circuits.
They consist of two coils of wire, called the primary and secondary coils, wrapped around a magnetic core.
When an alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.
Transformers are used in power distribution systems, electronic devices, and many other applications.
Examples of transformers include step-up transformers, step-down transformers, isolation transformers, and autotransformers.
