The electrical conductivity of metal dec...

The electrical conductivity of metal decreases with rise in temperature, while that of a semiconductor increases. Explain

Text Solution

Verified by Experts

Electrical conductivity of metal decreases with rise of temperature. Because on heating the positive ions of the metal atoms start vibrating and produce hinderance in the flow of electrons. The electrical conductivity of semiconductors increases with increase in temperature because more electrons can jump to the conduction band
