Figs. 179 and 180.—Arrangement in series. The same battery joined in parallel (247) would give: E C (2) + R since we really form one giant cell, whose E. M. F. is thesame as a single cell, but whose internal resistance is reducedin proportion. ELECTRIC CURRENTS 269 We reduce this last formula to… … Figs. 181 and 182.—Arrangement in parallel. paring (1) and (3) we see that they have the same numer-ator, n E. The whole question turns then upon the valueof the denominators. One is nr -\- B, and the otherr-\-nR. If r is less than B, we can better afford to mul-tiply r by n, and so we choose the…
