1. By increasing the temperature, the specific resistance of a conductor and a semiconductor(a) increases for both(b) decreases for both(c) increases, decreases respectively(d) decreases, increases respectively.

Answer»

Thespecific resistance of a conductoris directly proportional totemperature. It means that if thetemperature increasesthenresistancealsoincreasesIn case ofsemiconductorsas thetemperatureincreases the electrons in the valence band get excited and jump into the conduction band and hence the conductance increases resulting in the dwindling ofresistance.
