Product Description

This Eureka/Constantan Bare Wire is a copper-nickel alloy with a low temperature coefficient of resistance, making it well suited for resistance coils, heating elements, and resistance-thermometry demonstrations. Supplied bare (uninsulated) on a 125g reel of 30 SWG (0.31mm) wire — ideal for student physics experiments on resistance, Ohm's law, and the relationship between wire length, gauge, and resistance.
