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.

Resistivity - Isaac Physics

2021-11-4 · Resistivity depends on the temperature of the material. At a constant temperature, we can assume the resistivity is a constant, and use Ohm's Law which states that the resistance will be constant. This assumes the the current is not so large that it would heat up the material significantly.

Resistivity and Resistance – University Physics Volume 2

Resistivity. When a voltage is applied to a conductor, an electrical field is created, and charges in the conductor feel a force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. This dependence can be very complex. In some materials, including metals at a given temperature, the current density is approximately ...
