Description : What is the basic principle of operation of a transformer? (A) Self-induction (B) Mutual-induction (C) Static-induction (D) Dynamic-induction
Last Answer : B. Transformer works on principle of MUTUAL INDUCTION. When voltage is applied to the primary winding of the transformer, current flows through the current called magnetising current results in ... . Thus power flow from primary to secondary circuit is simply based on the mutual induction.
