Question
Glass is the _____ of electricity
- Conductor
- Semiconductor
- Insulator
- Neutral
Hint:
- Material like glass has no free electrons and in the absence of free or delocalized electrons, it is unable to conduct electricity.
The correct answer is: Insulator
- 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.
- In comparison, a material like glass has no free electrons and in the absence of free or delocalized electrons, it is unable to conduct electricity.
- So glass is Insulator
