Transformer works on the principle of
A
Back emf
B
Mutual Induction
C
Self Induction
D
None of these
Answer
Mutual Induction
Explanation
Solution
A transformer operates on the principle of mutual induction. An alternating current in the primary coil produces a varying magnetic flux, which links with the secondary coil and induces an electromotive force (EMF) in it. This process of inducing an EMF in one coil due to a changing current in a nearby coil is known as mutual induction.
