osite in direction to that of the charging current; that is,its E.M.F. pushes back against the E.M.F. of the chargingcells. It was for this reason that the ammeter reading fell.When the charging current is removed, this cell acts exactlylike a inimary galvanic cell and furnishes a current until… … the making with a much thicker coat of the active material (lead peroxide on the positive plate and a porous, spongy lead on the negative) than can be formed by a single charging such as we used. This material is pressed into interstices in the plates, as shown in Fig. 292. The E.M.F. of the lead…
