why wheatstone Bridge is not suitable for measuring very high resistance
Answers

when resistance gets very high, the currents that would flow if the bridge was unbalanced become very small, and this may make them hard to detect by the galvanometer.
Hence, as resistance increases, your ability to measure it accurately with a bridge decreases.

Answer:
Low Resistance: Wheatstone Bridgecan not be used to measure lowresistance because then the wireresistance and lead resistance come into the picture and affect the result. High Resistance: In wheatstone bridge, one balance the bridge by nullifying the deflection of the galvanometer.
