Question

What is the effect of temperature on resistivity of a substance?

Answer 1

Answer:

Resistivity is indirectly proportional to the temperature. In other words, as you increase the temperature of materials, their resistivities will decrease.

Answer 2

Answer:

The specific resistance or resistivity of a material depends on temperature. The change in temperature affects the resistivity of a material in the same way as it affects the resistance.The resistivity of metals increases linearly with the increase in temperature.

Temperature Dependence of Resistivity. ... Thus when the temperature is increased in a semiconductor, the density of the charge carriers also increases and the resistivity decreases.
