Q.
As the temperature increases, the electrical resistance [2022]

1 increase for both conductors and semiconductors

2 decreases for both conductors and semiconductors

3 increases for conductors but decrease for semiconductors

4 decreases for conductors but increases for semiconductors

Ans.
(3)

The temperature coefficient of resistance ( $α$ ) is positive for conductors and negative for insulators.

So, as the temperature increases, the resistance of conductor increases and for semiconductors decreases.

Solution
