Here's why:
* Coils: Transformers use two coils of wire, a primary coil and a secondary coil.
* Iron Ring: The iron ring, called a core, helps to concentrate the magnetic field produced by the primary coil. This magnetic field then induces an electromotive force (EMF) in the secondary coil.
The primary coil receives an alternating current (AC) input, which creates the changing magnetic field. The secondary coil then picks up this changing magnetic field and outputs a different voltage, depending on the number of turns in each coil. Transformers are essential in electrical systems for changing the voltage of AC power.
