Question

The principle of working of a transformer

• A. self-induction
• B. electrostatic induction
• C. magnetic induction
• D. mutual induction

Answer 1

Answer:

D. mutual induction

• A transformer is an electrical device used to change alternating current (AC) voltage levels.

• It operates on the principle of mutual induction, where a changing current in the primary coil creates a changing magnetic field that, in turn, induces an electromotive force (EMF) or voltage in the secondary coil.
