NEETChemistrySolid State
How does the electrical conductivity of semiconductors change with increasing temperature?
Options
- AIt remains constant.
- BIt decreases.
- CIt increases.
- DIt becomes zero.
Correct answer
C. It increases.
Step-by-step solution
The electrical conductivity of semiconductors increases with rising temperature because more electrons can jump to the conduction band, leading to enhanced conductivity.
