At room temperature, an intrinsic silicon crystal acts approximately as_______________?
Correct answer: C. An insulator
- A. A battery
- B. A conductor
- C. An insulator
- D. A piece of copper wire
Explanation
Pure silicon has very few free charge carriers at room temperature, so its conductivity is low and it behaves approximately as an insulator. Doping is used to increase its conductivity.
