We have talked about step-up or step-up down transformer in my previous article.
Do you know what exactly transformer is?
Transformer is a static device which works on the principle of "Induction Machine",i.e., whenever a flux linked with the conductor changes an emf (electro-motive force) induced in the circuit. Sinusoidal signal i.e,alternating signal is applied to the transformer.It changes the voltage from low to high value or vice-versa.
