e/Liquid rheostat

Information
has gloss	eng: A liquid rheostat or salt water rheostat is a type of variable resistor. It consists of a tank containing brine in which electrodes are submerged to create an electrical load. The electrodes may be raised or lowered into the liquid to respectively decrease or increase the electrical resistance of the load. To stabilize the load, the mixture must not be allowed to boil. The salt water rheostat operates at unity power factor and was widely used by generator assemblers, until 20 years ago, as a matter of course. They are still constructed for the commissioning of large diesel generators in remote places, where discarded oil drums and scaffold tubes typically form the tank and electrodes.
