Inductors are our other energy-storage element, storing energy in the magnetic field, rather than the electric field, like capacitors. In many ways, they exist as duals of each other. Magnetic field for one, electric for the other; current based behavior and voltage based behavior; short-circuit style behavior and open-circuit style behavior. Many of these
