Solution
Verified by Toppr

From wheatstone bridge while measuring For resistances of very low value like few ohms , the effect of other components of the circuit like wires , galvanometer etc. might come into account. these components might introduce stray resistance to the calculation
.Therefore we cannot apply wheatstone bridge for low resistance.
