Options

  1. Aself-induction
  2. Belectrical inertia
  3. Cmutual induction
  4. Dmagnetic effect of electric current

Correct answer

C. mutual induction

Step-by-step solution

A transformer works on the principle of mutual induction. Mutual induction is a property of two coils in which an emf is induced in a coil by a change of flux due to changing current in an adjacent coil.
