This process is called ?Formation of the cell^ and it igS ELECTRICITY CH. XII. is said to be left charged; this is represented in fig. i. Subse-quent chargings will need only a single passage of the Dischaj-ging the cell. In our discussion of the cell we will at present consider only thedegree of oxidisation of the lead, and will only touch on the partplayed by the dilute acid. It is clear that if we have PbO, the form-.
