Inductors, frequently called chokes, are passive components that accumulate energy inside a magnetic field . They generally consist of a coil of wire, and their function is defined by the inductance value, measured at Henrys (H). Essentially , when current passes through an inductor, it produces a magnetic field that impedes changes in that current. This feature is what allows inductors valuable in a wide range of power circuits for shaping signals and saving energy.
