Question

what happens when the temperature increase in the case of semiconductor and conductor?​

Answer 1

When temperature is increased in case of a semiconductor the free electron gets more energy to cross the energy gap to the conduction band from the valence band.so now more electrons can go easily to the conduction band so resistance decreases with temperature.

hope this helps u make me brainliest and thank me if this helps u
