Copper can also maintain solidity at 1083C and boils at 2567C. Like most metals, as the temperature goes up, so does the resistivity. Because of these factors, copper is widely used for electrical purposes such as household electrical wires, electrical machinery and generators and is able to withstand the elements to be used in outdoor power lines.

Jul 11, 2018· Resistivity units and conductivity units. Resistivity ρ, unlike resistance, is an intrinsic property of a material.It means that it doesn't matter whether the wire is thick or thin, long or short. The resistivity will always be the same for a specific material, and the resistivity units are "ohm meter" (Ω * m).The higher the resistivity is, the more difficult it is for the current to flow
