Background

An Inductor (Inductor) is a component that can convert electrical energy into magnetic energy for storage. The inductor is similar in structure to a transformer, but has only one winding. The inductor has an inductance that only impedes the change in current. If the inductor is in a state where no current is passing, it will try to block the current from flowing through it when the circuit is on; if the inductor is in a current passing state, the inductor will try to keep the current unchanged when the circuit is opened. The inductor is also called choke, reactor, dynamic reactor, the most original inductor is iron core coil used by british m. A paper on the phenomenon of self-induction was published in us j. The unit of inductance is called henry, henry for short. In the middle of the 19 th century, inductors have been put to practical use in devices such as telegraph and telephone.
