Transformer is based upon the principle of mutual induction. It consists of two coils, primary coil (p) and
secondary coil (s), insulated from each other wounded on soft iron core. Often the primary coil is the input coil
and secondary coil is the output coil. These soft iron cores are laminated to minimise eddy current loss.​
