LED Backlight Jiangsu Manufacturer Direct Supply, Wholesale, Customization, Purchase [Nanjing Weishiboke Electronics Co., Ltd.] Inductor (Inductor) is an element that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer but has only one winding. An inductor has a certain inductance and only resists changes in current. If an inductor is without current passing through it, when the circuit is closed, it will try to resist the current flowing through it; if an inductor has current passing through it, 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 circuit, meaning that when the current passing through a closed circuit 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 circuit itself. If the current in a closed circuit changes and induces an electromotive force in another closed circuit due to induction, this type of inductance is called mutual inductance. Inductance is the alternating magnetic flux produced around a conductor when alternating current passes through it, the ratio of the magnetic flux of the conductor to the current producing the flux. When direct current passes through an inductor, it only presents fixed magnetic field lines that do not change over time.
