Question

The electrical resistance of metals : (a) increases with an increase in temperature (b) decreases with an increase in temperature​

Answer 1

Answer:

B. Decreases with an increase in temperature

Explanation:

Answer 2

Answer:

Increases with an increase in temperature.

Explanation:

The resistance of a conductor increases with an increase in temperature because the thermal velocity of the free electrons increases as the temperature increases. This results in an increase in the number of collisions between the free electrons.
