Materials that conduct electricity are called conductors of electricity. Copper is a metal which conducts electricity.
You have already learnt about conductors and non-conductors in Year 3. Can you name two conductors and two non-conductors?
- Metals that conduct heat are called heat conductors. An example of a heat conductor is steel.
- Materials that do not conduct electricity are called insulators. Plastic materials are insulators of electricity.
- Materials that do not conduct heat are called heat insulators. Materials such as plastic and wood do not conduct heat. They are called heat insulators.
Do You Know?
Good conductors of heat are also good conductors of electricity.
