Text Solution
Verified by ExpertsThe correct answer is:
A
Step 1: Understand the principle behind a transformer. A transformer works on the principle of electromagnetic induction, specifically involving mutual inductance between two coils of wire.
Step 2: In a transformer, an alternating current (AC) in the primary coil creates a changing magnetic field, which induces an electromotive force (EMF) in the secondary coil through mutual inductance.
Step 3: Self inductance refers to the induction of EMF in the same coil due to a changing current, while Ampere's law relates to the magnetic field around current-carrying conductors, and Lenz's law pertains to the direction of induced EMF.
Therefore, the correct answer is Mutual inductance (Option A).
