The main problem being that not all copper has the same resistivity value, so, for ief, a 4mm 2 conductor from two different suppliers may have different resistance values. When you use our service you can be assured the latest editions and easy access. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameterbecause the cross section is directly proportional to its strength and weight, and inversely proportional to its resistance.
