Constantan vs. Resistivity

Constantannoun

An alloy of copper and nickel whose resistivity is constant over a wide temperature range.

Constantannoun

a copper-nickel alloy composed of approximately 55 per cent copper and 45 per cent nickel, with high electrical resistance and a low temperature coefficient; it is used as resistance wire and in thermocouples.

Constantannoun

a copper-nickel alloy with high electrical resistance and a low temperature coefficient; used as resistance wire

Constantan

Constantan is a proprietary name for a copper–nickel alloy also known as Eureka, Advance, and Ferry. It usually consists of 55% copper and 45% nickel.

Resistivitynoun

(electricity) The resistance offered at a particular temperature by an electrical conductor of any given material in a cube of unit length, expressed in ohm-metres (Ωm) in the metric system of measurement.

Resistivitynoun

(thermodynamics) The reciprocal of thermal conductivity, having SI unit: m K W-1

Resistivitynoun

a material's opposition to the flow of electric current; measured in ohms
