The length of potentiometer wire is 5m. It is connected to a battery of constant emf..for a given leclanche cell, the position of galvanometer deflection is obtained 100 cm. If the length of the potentiometer wire be made 8 m instead of 5m, calculate the length of wire for zero deflection in galvanometer for same cell.

Expert Answer
It will be proportional in these two cases.
so now the deflection will be obtained at=8/5 x 1= 1.6m
