EM5.2 Induction Coils

An inductor stores current. Three inductors in series are in parallel with a light bulb. As the switch is on, the inductors store current and the light is on. The current through the inductors is greater than that through the lamp. As the light is turned off, the current stored in the inductors is released and flows through the light only. Thus, when the power is turned off, the bulb flashes brightly for a split-second and then shuts off, after the inductors have discharged their current.
