Question

what will happen to the electrical resistance of a conductor if the temperature of the conductor decreases​

Answer 1

• Heating a metal conductor makes it more difficult for electricity to flow through it. These collisions cause resistance and generate heat.Heating the metal conductor causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance.

Answer 2

Answer:

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