EI 57 35 Power Transformer

What is transformer ?

Electrical power transformer is a static device which transforms electrical energy from one circuit to another without any direct electrical connection and with the help of mutual induction between two windings. It transforms power from one circuit to another without changing its frequency but may be in different voltage level.

In most countries of the world, electricity available from a wall outlet is 110 or 220 volts. Many electronic devices require much lower voltage to operate. Transformers that are used to supply proper voltage to electronic devices are referred to as transformers.
