Question

PVC is used to coat wires used in home wiring. Which property is responsible for it?

• A. Bad conductor of electricity.
• B. Low melting point
• C. Low boiling point
• D. Lustrous

Answer 1

The correct option is A

Bad conductor of electricity.

PVC (Polyvinyl chloride), being a covalent compound, is a bad conductor of electricity. It is wrapped around electric wires so that two wires can be crossed around one another.

Also, if a person touches the wire while the switch is on, he will not get an electric shock as PVC acts as a barrier. Thus, it is used in coating wires.
