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
