Q: What happens to the resistance of a semiconductor with an increase in temperature? (2023)

Solution: The resistance of a semiconductor decreases with an increase in temperature due to the increased number of charge carriers.

Steps: 6

Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions, like silicon.
Step 2: Know that resistance is a measure of how much a material opposes the flow of electric current.
Step 3: Learn that in semiconductors, temperature affects the number of charge carriers (electrons and holes).
Step 4: Realize that when the temperature increases, more charge carriers are generated in the semiconductor.
Step 5: Understand that with more charge carriers available, the semiconductor can conduct electricity better.
Step 6: Conclude that as a result, the resistance of the semiconductor decreases when the temperature increases.
