|||
|
a) |
Less than that of an insulator |
b) |
Is equal to zero |
|
c) |
Is equal to infinity |
d) |
More than that of an insulator |

b) |
Is equal to zero |
|
c) |
Is equal to infinity |
d) |
More than that of an insulator |
|
(b) The conductivity of an intrinsic semiconductor decreases with decrease in temperature and so it behaves as an insulator at 0 K. The conductivity of an insulator is zero. Therefore, the electrical conductivity of an intrinsic semiconductor at 0 K is equal to zero. |
