Question
Copper is the ___________ of electricity.
- Insulator
- Conductor
- Neutralizer
- Semiconductor
Hint:
There is large number of free electrons in copper, as in other metals
The correct answer is: Conductor
- A conductor allows current to flow easily through it. Insulators don't allow current to flow through it. Electric charges are absent in insulator. Conductors are used in making electrical equipment.
- The presence of a large number of free electrons in copper, as in other metals, is what makes it a good conductor of electricity.
