There is a definite potential difference between the two ends of a potentiometer. Two cells are connected in such a way that first time help each other, and second time they oppose each other. They are balanced on the potentiometer wire at 120cm and 60cm length respectively. compare the electromotive force of the cells. potentiometer wire at 120cm and 60cm length respectively. Compare the electromotive force of the cells.
