esting onthe copper strip acting asa porous partition be-tween the fluids. Thezinc stands in a solutionof zinc sulphate, or a weaksulphuric acid solution.The internal resistance islow, and the current large,being from i to 5 am-peres. These cells are theideal bluestone cells for charging… … Fig. 6t. 194 Batteries for Coils, battery. The voltage not being over i volt,however, renders these cells hardly suitablefor direct connection. Five cells connectedin multiple would give all of lo amperes ofcurrent, and i volt, and a number of thesemultiple groups could be connected in seriesfor a…
