Question

In a semiconductor
  1. There are no free electrons at any temperature
  2. The number of free electrons is more than that of the conductor.
  3. There are no free electrons at 0K
  4. None of these

A
There are no free electrons at any temperature
B
The number of free electrons is more than that of the conductor.
C
None of these
D
There are no free electrons at 0K
Solution
Verified by Toppr

In semiconductor, there are fewer electrons than that of a conductor.
But, at 0K, i.e., at the absolute zero temperature, there can not exist any free electrons. This is also true in the case of any conductor.
