Question

Which of the following is a function of an inductor?

A.

It allows the flow of current

B.

It opposes the flow of both AC and DC

C.

It opposes the flow of AC

D.

It opposes the flow of DC

Correct option is C


An inductor is a passive electronic component that resists changes in current. Its primary function is to oppose any change in current, and it exhibits different behaviors when exposed to AC (alternating current) and DC (direct current).
An inductor opposes changes in current, and for AC, the resistance to current flow increases with frequency. This is called inductive reactance. In AC circuits, the inductor creates a back EMF (electromotive force) that opposes the flow of current, thus limiting the amount of current that can pass through.
