alleryAt room temperature, the conductivity of an intrinsic semiconductor is:
AVery low
BVery high
CQuite fixed
DFully zero
Answer & Solution
Correct answer: A. Very low
1. Its conductivity depends on temperature.
2. At ordinary temperatures few electrons are excited.
3. So the conductivity is very low.
