How do the electrical conductivity and resistivity of metallic conductors, semi-conductors, and super conductors vary with temperature ?

Text Solution

Verified by Experts

Electric conductivity of metallic conductors and super conductors decreases with increase of temperature while resitivity inceases.
Electrical conductivity of semiconductors increases with the increase of temperature because more electrons can jump from valence band to conductance band. The resistivity decreases.
