Do you know about transformer?

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 the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, known as the primary and secondary coils, wrapped around a magnetic core.
When an AC voltage is applied to 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 include step-up transformers used in power plants to increase voltage for long-distance transmission, and step-down transformers used in electronic devices to decrease voltage for safe use.
