Why does we use manganian or constantan material for making of potentiometer wire?
Verified Answer
Why does we use manganian or constantan material for making of potenti...
Potentiometer is used to measure potential difference. A wire made of manganin has very low temperature coefficient of resistance.
We also know that the voltage drop V across the potentiometer is directly proportional to the length l of the wire.

That is V ∝ l

Hence resistance may reduce the potential drop if copper or any other material with high temperature coefficient of resistance is used to make the potentiometer wire.
