Can we measure a resistance of the order...

Can we measure a resistance of the order of `0.160 Omega` using a Wheatstone's bridge ? Support your answer with reasoning.

No, the resistance of the connecting wires is itself of the order of the resistance to be measured. It would create uncertainty in the measurement of low resistance.
