A certain material has a resistivity of 7.8 *10³ $\Omega$.m at room temperature, and its resistivity decreases as the temperature is raised by 100°C.The material is most likely: A)a metal B)a pure semiconductor C)a heavily doped semiconductor D)an insulator E)none of the above

Question

Quizplus · Accepted Answer

The decrease in resistivity with an increase in temperature is characteristic of semiconductors, as thermal energy excites more charge carriers.

A Certain Material Has a Resistivity of 7 Ω\OmegaΩ M at Room Temperature, and Its Resistivity Decreases as the .M
