A) less than that of an insulator
B) is equal to zero
C) is equal to infinity
D) more than that of an insulator
E) is equal to that of a metal
Correct Answer: B
Solution :
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.You need to login to perform this action.
