The operational principle of transformer is based on
A
Electromagnetic induction
B
Newton's law
C
Electromagnetic effect
D
Ampere's law
Answer
Electromagnetic induction
Explanation
Solution
Transformers operate on the principle of electromagnetic induction. An alternating current in the primary coil creates a changing magnetic flux, which then induces an electromotive force in the secondary coil due to mutual induction. Faraday's Law of Electromagnetic Induction is the key principle at play.
