Question

Why it is generally preferred to obtain the balance point in the middle of the meter bridge wire?

Answer 1

$\textbf{Hey there}$!!


$\textbf{Answer}$:


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.

Hey !!

To obtain the balance point in the middle of the meter bridge wire because meter bridge is most resistive when all four resistances are of same order.

Good luck !!
