MHT CET · Physics · Alternating Current
The alternating e.m.f. induced in the secondary coil of a transformer is mainly due to
- A varying electric field
- B varying magnetic field
- C the iron core
- D heat produced in the coil
Answer & Solution
Correct Answer
(B) varying magnetic field
Step-by-step Solution
Detailed explanation
The secondary coil experiences an emf as a result of the changing magnetic field. Therefore, a changing magnetic field is primarily responsible for the transformer voltage that is induced in a transformer's secondary coil.
