A dimmer consisted of a glass jar filled with salt water with a metal electrode at each end. As the upper electrode was moved away from the lower [3] electrode, the resistance increased and the lights got dimmer. [4] [5] [6] The brightness also depended on the concentration of salt in the water. [4]
A liquid rheostat or water rheostat [1] or salt water rheostat is a type of variable resistor. This may be used as a dummy load or as a starting resistor for large slip ring motors. In the simplest form it consists of a tank containing brine or other electrolyte solution, in which electrodes are submerged to create an electrical load.
Early examples of a rheostat dimmer include a salt water dimmer, a kind of liquid rheostat; the liquid between a movable and fixed contact provided a variable resistance. The closer the contacts to each other, the more voltage was available for the light.
