The balancing lengths for the cells of e.m.f. `E_(1)` and `E_(2)` are `l_(1)` and `l_(2)` respectively. If they are connected separately then

The balancing lengths for the cells of emfs E_1 and E_2 are l_1 and l_2 respectively . If they are connected separately then

In a potentiometer experiment the balancing length is 8 m, when the two cells E_(1) and E_(2) are joined in series. When the two cells are connected in opposition the balancing length is 4m. The ratio of the e.m.f. of two cells (E_(1)//C_(2)) is
