Question

Why are connecting wires made of metals ? Why do they have rubber covering ?

Answer 1

1. Conductors are the materials that allow the passing of electricity across them.
2. The insulator is a material that does not allow electricity to pass through them.
3. Metals are good conductors that's why we make electrical wires using metals.
4. Rubbers are insulators. They do not allow electricity to pass across them.
5. That's why rubbers are used to cover electrical wires so that we get protection from electrical shocks.
