The alternating voltage induced in the secondary coil of a transformer is mainly due to

A

a varying electric field

B

transformer core

C

constant current

D

varying magnetic field

Text Solution

Verified by Experts

The correct Answer is:
D
Transformer works on the principle of mutual induction between the primary and the secondary coils. Varying magnetic field is chiefly responsible for voltage across secondary.
