Transformer is an electrical device used to transfer electrical energy from one device to another, mostly with a difference in voltage. It wounds two coils of insulated wires and works only with AC (alternating current). It is employed in places where there is a need to increase or reduce the voltage of electricity. Transformers are equipped in many household devices like TV, stereo devices, etc.
