The resistivity of a pure semiconductor
A) increases with an increase in temperature.
B) increases with a decrease in temperature.
C) is constant over a wide range of temperatures.
D) is zero at room temperature.

Question

Quizplus · Accepted Answer

The resistivity of a pure semiconductor increases with a decrease in temperature because as temperature decreases, fewer charge carriers are available for conduction, thus increasing resistivity.
