Nanjing LED Backlight Manufacturer, Wholesale Price, How Much, Which One is the Best [Wanshi Bo Electronic Co., Ltd.]: An inductor is an element that converts electrical energy into magnetic energy and stores it. The structure of an inductor is similar to a transformer but has only one winding. An inductor has a certain inductance and only resists changes in current. If an inductor is not carrying current and the circuit is closed, it will try to resist the current flowing through it; if the inductor is carrying current and the circuit is opened, it will try to maintain the current constant. Inductors are also known as chokes, reactors, and dynamic reactors. Inductance is an attribute of a closed circuit, meaning that when the current through a closed circuit changes, an electromotive force appears 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, due to the induced effect, an electromotive force is generated in another closed circuit, and this type of inductance is called mutual inductance. Inductance is the alternating magnetic flux produced around a conductor when AC current flows through it, which is the ratio of the magnetic flux of the conductor to the current producing it. When DC current flows through an inductor, it only presents fixed magnetic lines of force around it, which do not change over time.
