The resulting electro-motive force is the electro-motive forceof one cell only, while the resistance equals that of one cell divided by ELECTEICITY AND MAGNETISM. 13 the total number of cells. Tlie amperage is equal to the product of thenumber of cells by the amperage of each individual cell. (3) Group.—In the group method some (Fig. 4) cells are joinedin series and some are in parallel.
