Question

What is Wheatstone bridge ? Explain its principle.
​

Answer 1

Answer:

Definition: The device uses for the measurement of minimum resistance with the help of comparison method is known as the Wheatstone bridge. ... The Wheatstone bridge works on the principle of null deflection, i.e. the ratio of their resistances are equal, and no current flows through the galvanometer

Answer 2

Answer:

the answer is

Explanation:

The device uses for the measurement of minimum resistance with the help of comparison method is known as the Wheatstone bridge. The value of unknown resistance is determined by comparing it with the known resistance. The Wheatstone bridge works on the principle of null deflection, i.e. the ratio of their resistances are equal, and no current flows through the galvanometer. The bridge is very reliable and gives an accurate result.
