In AC circuits, what is an inductor primarily used for?

An inductor is primarily used in AC circuits to store electrical energy in a magnetic field when current flows through it. When the current changes, the magnetic field collapses, and the inductor releases this stored energy back into the circuit. This property of storing energy is particularly important in applications such as filters, oscillators, and inductive loads.

In contrast to other components, inductors react to changes in electrical current, which allows them to play a crucial role in managing AC signals. While they can indirectly affect current and work with impedance, their primary function revolves around energy storage. This distinction highlights the unique role of inductance in AC circuit design and operation.
