In a potentiometer experiment it is found that no current passes through the galvanometer when the terminals of the cell are connected across 125 cms of the potentiometer wire On shunting the cell by a 2W resistance the balancing length reduces to half The internal resistance of the cell is A 4W B 2W C 1W D 0 5W
