As the temperature increases, the electrical resistanceNEET 2022 (Phase 1)

Answer:

Solution:

For conductors, on increasing temperature, thermal agitation of free electrons increases. Hence, resistance increases.

For Semiconductors, number of holes or charge carriers increases with increase in temperature.

Hence, resistance increases for conductors but decreases for semiconductors.

$\Rightarrow$ Answer is (b)
