Name any one material having a small value of temperature coefficient of resistance. Write one use of this material?

1 Answer

by EE-Expert answered 2 months ago

Material: Manganin (an alloy of copper, manganese, and nickel)

Use: Due to its very low temperature coefficient of resistance, it is used to make precision wire-wound resistors and shunts for electrical measuring instruments like ammeters and Wheatstone bridges, where a stable and predictable resistance is essential.
