Resistivity of Copper - The Physics Factbook

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.

Table of Electrical Resistivity and Conductivity

Jun 27, 2019  Electrical resistivity, represented by the Greek letter ρ (rho), is a measure of how strongly a material opposes the flow of electric current. The lower the resistivity, the more readily the material permits the flow of electric charge. Electrical conductivity is the reciprocal quantity of resistivity. Conductivity is a measure of how well a ...
