constantan
/ˈkɑnstənˌtæn/
noun
- A copper-nickel alloy that has a nearly constant electrical resistance over a wide range of temperatures, used in electrical components.
- Unlike pure copper, constantan does not change its electrical resistance much when heated.
- Constantan is often used in thermocouples because its resistance stays stable with temperature changes.
- The engineer selected constantan wire for the precision resistor in the circuit.
