Inductors, frequently called chokes, embody passive components that accumulate energy inside a magnetic domain . They typically consist of a coil of wire, and their characteristic is defined by the inductance value, measured in Henrys (H). Basically , when current passes through an inductor, it creates a magnetic field that impedes changes in that current. This property is what enables inductors valuable in a wide range of power circuits for shaping signals and conserving energy.
