- Need help with this questionarrow_forwardInductors are fundamental components in electronics and electrical circuits. They are passive devices that store energy in the form of a magnetic field when crossed by an electric current. Inductors consist of a wire wound around a core, often made of iron or another ferromagnetic material.
