Inductors, frequently called chokes, are passive parts that retain energy through a magnetic domain . They typically consist of a loop of wire, and their behavior is defined by the reactance value, measured at Henrys (H). Essentially , when current runs through an inductor, it generates a magnetic field that resists changes of that current. This property is what makes inductors useful in a vast range of electrical circuits for shaping signals and conserving energy.
