Question

How do you except the conductvity vary in a metallic conductor with increasing temperature?Explain

Answer 1

Explanation:

If the temperature is increased more electrons free themselves from the parent atom and hence, the conductivity increases as the temperature is increased. In semiconductors number of free electrons increase while the mobility increases little.

Answer 2

Explanation:

In increasing the temperature, the metal conductvity conductivity decreases because the resistivity of conductor increases with increasing temperature which causes obstacles for flow of current
