Question

graphically represent the variation of resistivity of a semiconductor with absolute temperature​

Answer 1

Answer:

As the temperature of the semi-conductor is increased, the electrons in the valence band gain sufficient energy to escape from the confines of their atoms. As a result, in higher temperatures, a semi-conductor's valence electrons are free = conduction results, resistivity decreases.
