Question

why is it generally preferred to obtain the balance length near the mid-point of the bridge wire ?​

Answer 1

Answer:

The balance point is obtained in the middle of the bridge wire for the following reasons:

➡When the balance point is in the middle of the bridge wire, the resistance in the four arms P, Q, R and X become of the same order and consequently the bridge becomes more sensitive.

➡If some errors occurs in locating the balance point, the error in the measured value of the resistance will be comparatively smaller.

➡The error due to end resistance is reduced.
