MCQ
A transformer is based on the principle of
  • Mutual inductance
  • B
    Self inductance
  • C
    Ampere's law
  • D
    Lenz's law

Answer

Correct option: A.
Mutual inductance
a
(a) A transformer has got one primary coil, the change of current in which produces an induced emf in the secondary coil. Hence it is based on the principle of mutual induction.
