Question

Which of the following applications indicates that plastics are bad conductors of electricity?

• A. Buckets are made of plastics
• B. Electrical wires are covered with plastics
• C. Cooking pans have plastic handles
• D. Plastics are used to make packaging materials

Answer 1

Answer: (B)

Electrical wires are covered with plastics

Plastic does not allow electricity to pass through it, thus, is a bad conductor of electricity and is used as an insulator.
That's the reason why they are used to insulate electrical wires and prevent electrical shocks.

Plastics are light, durable, and bad conductors of heat and non-reactive. This makes them ideal for use as plastic foam core, handles of cooking pans and packaging material.

So, option B is correct.
