How to Calculate the Resistance of Copper Wire | Our Pastimes
There is a specific formula you can use to calculate the resistance of copper wire based on its area and length. To save time, a calculator comes in handy to crunch the numbers. The area of electrical wire is measured in a unit called "circular mils.'' You need this number to calculate a wire's resistance.

The formula to calculate wire resistance is as follows: in which R is the resistance (Ω), ρ is the resistivity of the material (Ωm), l is the length of the material (m), A is the cross-sectional area of the material (m 2)
Resistance wire - Wikipedia
Resistance wire is wire intended for making electrical resistors (which are used to control the amount of current in a circuit). It is better if the alloy used has a high resistivity, since a shorter wire can then be used.In many situations, the stability of the resistor is of primary importance, and thus the alloy's temperature coefficient of resistivity and corrosion resistance play a large ...
