y do we prefer to obtain the balance point between 35 - 65cm

Expert Answer
We should preferably obtain the balance point at the middle of wire ( say, in between 30 to 60 m ) , so as to get maximum accuracy. In this case the ratio of arms are nearly equal and the end resistances of copper strips also produce the least effect. Hence, the bridge is most sensitive.
