The structure of an inductor is similar to 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 an 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 when the current passing through a closed loop changes, an electromotive force will appear 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 induction, an electromotive force 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 AC current flows through it, the ratio of the magnetic flux of the conductor to the current producing the flux. When DC current flows through an inductor, it only presents fixed magnetic lines of force that do not change over time.
