Question
Polyvinyl chloride has a property that makes it suitable for coating electric wires at home. Choose the property from the following?
- It is a fine conductor of heat.
- It is a fine conductor of electricity.
- It conducts electricity poorly.
- It is cheap in cost.
Hint:
insulators.
The correct answer is: It conducts electricity poorly.
It conducts electricity poorly that's why to prevent short circuit and electricshock we use pvc to coat the wire.
