Question

An inductor is used in a circuit to oppose changes in _____ through it.

Answer 1

changes in current

When the current flowing through an inductor changes, the time-varying magnetic field induces an electromotive force (e.m.f.) (voltage) in the conductor, described by Faraday's law of induction. According to Lenz's law, the induced voltage has a polarity (direction) which opposes the change in current that created it.

Answer 2

Answer:

Answer :

• $\longmapsto$ changes in current
