Question

what is the reason behind covering wires carrying electricity with rubber in some places

Answer 1

This is because rubber is a poor conductor of electricity, and does not allow electric current to pass through it.

If the wires were not covered with rubber ( Or Plastic in many cases too), then the person using the wires is very likely to get an electric shock, which can also be fatal.

Hence, this rubber covering is used for safety only.
