The structure of an inductor is similar to that of a transformer but has only one winding. An inductor has a certain inductance, which only resists changes in current. If an inductor is in a state without current flow, when the circuit is closed, it will try to resist the current passing through it; if the inductor is in a state with current flow, when the circuit is opened, it will try to maintain the current unchanged. Inductors are also known as chokes, reactors, and dynamic reactors. Inductance is an attribute of a closed loop, meaning that when the current through a closed loop changes, an electromotive force (EMF) appears to resist the change in current. This type of inductance is called self-inductance, which is an attribute of the closed loop itself. If the current in a closed loop changes, due to the induced effect, an EMF is generated in another closed loop, and this type of inductance is called mutual inductance. Inductance is the alternating magnetic flux produced around the conductor when alternating current flows through it, the ratio of the magnetic flux of the conductor to the current that produces it. When direct current flows through an inductor, only fixed magnetic lines of force are present around it, which do not change over time.
