Today we study about most important type of Electrical Engineering
Electrical Machine
In electrical machine we study about Transformer.
What is transformer?
Transformer is an static device which converts a power in electrical device from one circuit to another circuit is called transformer.
Principle of Transformer
A transformer consists of two electrically isolated coils and apply on Faraday's law of “mutual induction" in this EMF [Electromagnetic field] is induced in the transformer secondary coil by the magnetic flux generated by the voltages and currents flowing in the primary coil winding.
There are two types of transformer:
1. Step up Transformer
2. Step down Transformer
