Transformers work on the principle of electromagnetic induction to transfer electrical energy from one circuit to another.

• Transformers have two coils of wire, a primary coil and a secondary coil, 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.

• The voltage induced in the secondary coil is proportional to the ratio of the number of turns in the secondary coil to t...read more
