Resistance Alloys

Electrical resistance alloys are used to control or regulate either alternating or direct current. The electrical properties of interest are resistivity, temperature co-efficient of resistance (TCR) and thermoelectric potential. The first is a measure of the resistance to the flow of current in a metal or alloy; the second is a measure of the consistency of the resistance over a range of temperatures; the last defines the Electromotive Force (EMF) generated when two dissimilar metals are joined and exposed to a variation in temperatures.
