Increase in resistivity of metal where as decrease in resistivity of semiconductor with increase in temperature.
Explanation of Solution
In case of semiconductors when we increase temperature more number of electrons can move from valence band to
In case of metals or conductor when we increase temperature thermal speed of free electrons increases consequently the free electrons collide more frequently with the metal ions hence mean relaxation time decreases and resistivity of metals will increase.
