Inductors, also known as chokes, represent passive parts that retain energy inside a magnetic domain . They typically consist of a winding of wire, and their characteristic is defined by the inductance value, measured by Henrys (H). Basically , when current flows through an inductor, it produces a magnetic field that opposes changes of that current. This property is what makes inductors helpful in a broad range of electronic circuits for filtering signals and saving energy.
