Question

Contrast the temperature dependence of electrical conductivity in metals and semiconductors.

Answer 1

Answer:

• From the conductivity equation it is clear that, the electrical conductivity is inversely proportional to temperature which means that when temperature increases, conductivity of metals decreases and conductivity of metals increases with decrease in temperature.

Answer 2

The electrical conductivity of a semiconductor increases with increasing temperature, whereas the electrical conductivity of a metal decreases with increasing temperature.
