Question

15. Wheat Stone Bridge experiment is most sensitive, when:



(a) All four resistances are approximately equal

(b) One of the resistances is very high as compare to others

(c) One of the resistances is very low as compare to others

(d) Any two resistances are equal to infinity

​

Answer 1

Explanation:

The Wheatstone bridge is said to be more sensitive when its voltmeter will be showing 0 deflection, means it will be in a balanced condition, ie., all the four arms are of nearly of same order of magnitude.
