: Two cells having unknown e.m.fs. E₁ and E₂ (E₁ > 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 E₂ 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.
