Testing Storage Batteries 375 The Water Rheostat. For making test discharges on storage batteries it is usually necessary toprovide a special resistance for current regulation purposes. A form ofresistance extensively used for this purpose and one which can be very con-veniently constructed is known as the water rheostat. The principle uponwhich this form of rheostat is constructed is that of utilizing water as aresistance, there being two metal plates immersed in a tank of water and towhich plates are connected the wires of the discharge circuit. Thus, byvarying the distance between the two plates the resistance offered by thewater to the flow of current is also varied and the discharge current is CO c4^ ^ C3^0 d^ C±=Z) c=i=3 ci c^ 5T~^5TSwfoT^^T^l- »^> 1—rv_y ^^—I •^ V^ 1 ^— ^.-^ ? 1 >w/.
