If a change in current in one coil induces a potential difference in a second coil through
A) inductance
B) self inductance
C) mutual inductance
D) motor action

Question

Quizplus · Accepted Answer

The phenomenon described in the question is mutual inductance. Mutual inductance occurs when a change in current in one coil induces a potential difference in a second coil. This is different from self-inductance, which occurs when a change in current in a single coil induces a potential difference within the same coil. Motor action and inductance are not relevant to the phenomenon described.
