Transformers convert high voltage electricity to low voltage or vice versa.

• Transformers work on the principle of electromagnetic induction.

• They consist of two coils of wire, the primary and secondary, 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.

• This voltage can be either higher or lower than the input voltage, depending on the number of turns in each coil.
