Question

Wheatstones’s bridge cannot be used for measurement of very _______ resistances.

• A. high
• B. low
• C. low(or) high
• D. zero

Answer 1

The correct option is B low

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.
