Transformer
Transformer Transformer is a electrical machine and it transfer electric power from one circuit to another without change in frequency.It has no moving part in it. It has a very high efficiency .The efficiency above 10%. In the transformer basically work on the mutual induction between the two circuit linked by a common magnetic field. It consists two winding one is primary winding and other is secondary winding.In the primary winding electrical energy is feed from the AC.and in the secondary winding energy is receive. Both winding are physically isolated but coupled magnetically.
