JEE Main 2023 (31 Jan Shift 1)
Question
The effect of increase in temperature on the number of electrons in conduction band and resistance of a semiconductor will be as:
Choose an option
Show full solutionCorrect option: C
Correct answer
C increases, resistance decreases
Step-by-step explanation
In case of semiconductors as the temperature increases the electrons in the valence band get excited and jump into the conduction band and hence the conductance increases resulting in the decrease of resistance. Thus, as temperature increases, increases and resistance decreases.
