International standard of resistance for copper Article no: Unsourced material may be challenged and removed. The main problem being that not all copper has the same resistivity value, so, for example, a 4mm 2 conductor from two different suppliers may iiec different resistance values.
In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, 600228 than its diameterbecause the cross section is directly proportional to its strength and weight, and inversely proportional to its resistance.
