atever electromotive forces be introduced inthe branches, the current in the branch circuit EF (Fig. 157)is independent of any E.M.F. or resistance in the branchcircuit AB, while the current in AB is independent of E.M.F.and resistance in EF Hence if we include the battery ofunknown resistance in… … Fig. 157 As in the last case if the current be too strong for thegalvanometer, we can increase the resistance in the galvano-meter branch. *174- Method of comparing the E.M.F. of Cells.— We conclude this chapter with a method of comparing theE.M.F. of two constant cells by a method analogous to…
