Jiangsu LED Backlight Manufacturer, Wholesale, How Much, Which One is the Best [Nanjing Weishibo Electronic Co., Ltd.] Inductor is an element that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to a transformer but has only one winding. An inductor has a certain inductance, which only resists the change in current. If an inductor is without current passing through it, when the circuit is connected, it will try to resist the current flowing through it; if an inductor is with current passing through it, when the circuit is disconnected, 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 due to the induction effect, an electromotive force is generated in another closed circuit, this type of inductance is called mutual inductance. Inductance is the alternating magnetic flux generated around a conductor when AC current passes through it, the ratio of the magnetic flux of the conductor to the current that produces this flux. When DC current passes through an inductor, it only presents fixed magnetic lines of force around it, which do not change with time.
