TISM izing is effected so slowly that the cells cannot give a long-continued steady flow of current, and for that reason theyare called open-circuit cells. These cells are extensively usedfor ringing bells, for setting signals, for telephones, etc., wherethe work is intermittent and the cells have… … Fig. 6. — Carbon cell with zinc rod in sal ammoniac solution. may therefore be used continuously. Such cells are calledconstant or closed-circuit cells. The first method of depolarizing requires that the hydrogenbubbles be cleared off the positive plate as fast as they aredeposited upon it. This…
