Question
Silicon is the ________ of the electricity.
- Insulator
- Conductor
- Semiconductor
- None
Hint:
- A conductor allows current to flow easily through it. Insulators don't allow current to flow through it. Electric charges are absent in insulator.A semiconductor material has an electrical conductivity value falling between that of a conductor
The correct answer is: Semiconductor
- 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.
- A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass.
- Silicon is an inherent semiconductor. Its electrical conductivity lies between the pure conductor and the insulator. Germanium is another example of an endogenous semiconductor. Hence, the correct answer is semiconductor.
