ABSTRACT:
Liquid rheostat system especially a water rheostat, employing the principle wherein electrical energy may be dissipated in the form of heat, by passing the electrical current through a liquid resistor or electrolyte, and wherein the apparatus is reasonably portable, inexpensive, and economical to operate and maintain. The invention readily compensates in use for variations in respective resistivity of fresh and/or brackish waters in a test mixture whereby to provide sufficient initial resistance as well as an adequate range of control of resistance, while maintaining current density within the desired limits. In use the heat energy developed is absorbed and removed by the controllable water mixture which in operation of the rheostat system continuously flows out of the rheostat. This is accomplished in part by shaping electrode plates to increase the immersed area thereof, with preselected disposition of intermediate dielectric plates, so shaped as to decrease the length of the current path developed in the apparatus as the liquid level therein may be caused to rise as required during operation of the system.
