Bridge, potentiometer and coil uses of 24 SWG eureka wire

Laboratories use 24 SWG eureka wire as the slide wire on metre bridges and potentiometers, where its low temperature coefficient keeps the resistance per unit length steady during a practical, and to wind resistance coils of known value for circuit boards and resistance boxes.

  • Slide wire for metre bridges and potentiometers
  • Winding resistance coils for boards and resistance boxes
  • Resistivity and resistance-versus-length experiments
  • Comparing resistance across gauges from 16 to 34 SWG

Frequently asked questions

What diameter is the 24 SWG eureka wire?
It is 0.55 mm in diameter and is supplied at 125 g per reel.

Can it be used as a metre bridge or potentiometer wire?
Yes. 24 SWG is a common slide-wire gauge, and eureka is a copper-nickel alloy of low temperature coefficient; the Wheatstone bridges in the same range use a 24 SWG constantan wire.

Is the wire insulated?
No. It is bare wire, so coils must be wound with the turns kept apart or on an insulating former.
