​

Answer 1

Answer:

It can be proved that the bridge is most sensitive when all the four Resistances are of the same order. In a meter bridge the Resistances of the two parts of the wire are of the same order as the unknown and known resistances are of the same order.

Answer 2

Answer:

the bridge is balanced when the two pairs of resistance connected to the galvanometer bear the same ratio.this can happen even when all the four resistance are not of the same order . it can be proved that the bridge y more sensitive when all the four resistance are of the same order
