Two cells having unknown e.m.fs. E, and E, (E, > E2) are connected in potentiometer circuit so as to assist each other. The null point is obtained at 8.125 m from the highest potential end. When the cell E, is connected so as to oppose cell E1, null point is obtained at 1.25 m from same end. Compare e.m.fs. of two cells.
