Factors that affect the resistivity of nichrome wire

Definition
The electrical resistivity, or specific resistance, ñ, is the resistance between the opposite faces of a metre cube of a material.

Units
10-8 Ohm m

Notes
Values are quoted at 293-298 K and are given in the SI units of Ohm m. Values are often quoted in micro ohm cm and to convert to these units, multiply by 100 000 000. Most numbers are probably reasonably accurate to 2 significant figures where quoted but it is clear that you should expect values to depend upon your particular sa...
