Because electricity can only travel through metal.
yes!
Plastic wrapped around the wire is insulator. Not a conductor. That is why it is wrapped around the conductor wire.
No, plastic is not a good conductor of electricity. This is because plastic is an insulator, meaning it does not allow the flow of electrical current through it easily. Metals, on the other hand, are good conductors of electricity.
Plastic is a poor conductor of heat, so a plastic cup can be considered a good insulator. It will help to keep hot drinks hot and cold drinks cold for longer periods of time compared to a material that is a good conductor like metal.
Plastic is a poor conductor of electricity due to its insulating properties.
No, because plastic is an insulator making it a very bad conductor of heat.
No, plastic is actually an insulator and not a conductor of electricity. Metals such as copper and aluminum are commonly known as good conductors of electricity.
No, CD (compact disc) is not a good conductor of heat because it is made of polycarbonate plastic, which is a poor conductor of heat. As a result, CDs do not transfer heat efficiently.
Well, it's certainly a conductor, although not as good as aluminium or copper. On the other hand a plastic paper clip is not a conductor.
bowl is conductor
Because plastic isn't as good a conductor of heat as metal.
No.
