Question

Why are electric wires covered with plastic?

Answer 1

because plastic is the bad conductor of heat and electricity

Answer 2

Electric Wires are covered with plastic because of the following reasons:

• Plastic is a good insulator it does not allow current or heat to flow through it.
• Plastic ensures that the current flows only in the wire and not outside the wire.
• Plastic reduces the chances of getting shocked.
• Plastic provides insulation covering the wire.
• Plastic is the worst conductor of heat and light and it is nonresponsive towards heat and light.

Hence, due to these reasons, electric wires are covered with plastics.
