Question

Which material is used for the meter bridge wire and why?

Answer 1

Meter bridge is madeup of manganin as it has a high specific resistance 

Answer 2

Hey !!

This is done to minimize the percentage error in the value of the unknown resistance.

ALTERNATIVELY,

This is done to have a better ''balancing out'' of the effects of any irregularity or non-uniformity in the meter bridge wire.

This can help in increasing the sensitivity of the meter bridge circuit.

GOOD LUCK !!
