Why do they say that copper wires are more conductor than aluminium wires?
Copper is a more conductive material than aluminium, meaning that it allows electricity to pass through it more easily. This is due to the atomic structure of copper, which allows for the free movement of electrons.
Copper wires are preferred for electrical wiring because of their high conductivity. This means that less energy is lost when electricity passes through the wire, making it more efficient for powering devices and buildings.
While copper wires may have higher conductivity than aluminium wires, there are still some advantages to using aluminium in certain applications. Aluminium is lighter, cheaper, and more abundant than copper, making it a popular choice for overhead power lines.
The conductivity of copper and aluminium wires can be affected by several factors, including temperature, material purity, and wire thickness. Higher temperatures can decrease conductivity, while impurities in the metal can also hinder the flow of electricity.
In general, copper and aluminium wires cannot be used interchangeably because of their different conductivity levels. However, in some cases, aluminium wires can be substituted for copper wires, but it may require adjustments to the electrical system to account for the difference in conductivity.
