Question

Why is Copper most used for electrical wiring?

Answer 1

Copper:

1. Copper is a chemical element and is represented by the symbol $\mathrm{Cu}$.
2. It has an atomic number of 29.

Property:

1. Copper is less oxidative than other metals, which prevents it from corrosion while still allowing it to carry electricity.
2. Copper is less oxidizing and has a lower resistance.
3. Metals having a low resistance will have a higher conductivity.
4. Copper is metal and thus can be drawn into thin wires (ductile).

Hence, Copper is mostly used for electrical wiring.
