Jiangsu LED Backlight Manufacturer, Customization, Supplier, Price [Nanjing Wanshi Bo 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 consists of only one winding. An inductor has a certain inductance, which only resists the change in current. If an inductor is in a state without current, when the circuit is closed, it will try to resist the current flowing through it; if an inductor is in a state with current, when the circuit is opened, it will try to maintain the current constant. Inductors are also known as chokes, reactors, and dynamic reactors. Inductance is a property of a closed loop, meaning when the current through a closed loop changes, an electromotive force appears to resist the change in current. This type of inductance is called self-inductance, which is the property of the closed loop itself. If the current in a closed loop changes and induces an electromotive force in another closed loop due to the inductive effect, this type of inductance is called mutual inductance. Inductance is the alternating magnetic flux generated around a conductor when AC current passes through it, which is the ratio of the magnetic flux of the conductor to the current producing the flux. When DC current passes through an inductor, it only presents fixed magnetic lines of force that do not change over time.
