transformer working on mutual induction

Answer / t.k.

Trasformer workes on the law of faraday emf= -dǾ/dt or you
can say principle of maganitic induction.

Answer / zahid

transformer works on the principal of mutual induction.That
is a changing currrent n one coil induce an e.m.f in another
coil.

Answer / vasudeva rao

transformer mainly works on the mutual induction principle.
