Interesting Nonlinear Effects
R. Stuart Mackay · Journal of Applied Physics · 1953
Series circuits of ordinary light bulbs and iron-core transformer coils are found to have properties of the different types of multivibrators and ring circuits. Besides their intrinsic interest value these circuits have application to a diversity of processes, e.g, switching, counting, and time delaying. They can all indicate their action and immediate state by switching on or off large incandescent lamps.
