The resistance of the pure semiconductor decreases in a certain ratio with the?
Correct answer: C. Increase in temperature
- A. Decrease in temperature
- B. Increase in current
- C. Increase in temperature
- D. Decrease in current
Explanation
In a pure semiconductor, the resistance decreases with an increase in temperature. This happens because as temperature increases, some electrons in the valence band gain enough energy to jump to the conduction band, leaving behind holes in the valence band. This increases the number of charge carriers in the material, leading to a decrease in resistance.
