Question

Silver is the metal with the highest conductivity, followed by copper, gold and aluminium. Why do you think copper and aluminium are used for electrical wire and cable rather than silver and gold?

Answer 1

Explanation:

Copper and aluminum are used for electric wires and cables because they are readily available and cheaper to produce.

The abundance of copper and aluminum is higher compared to silver and gold.

This makes the metals easier to mine than silver and gold. It would be impossible to use the scare amount of gold and silver to make electric wires and cables.

This use cannot be sustained.
