Vedclass · Answer

(D) transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction. It consists of two coils,the primary and the secondary,wound on a common magnetic core. When an alternating current flows through the primary coil,it creates a changing magnetic flux in the core. This changing flux links with the secondary coil and induces an electromotive force $(EMF)$ in it,which is the phenomenon of mutual induction. Therefore,a transformer works on the principle of mutual induction.
