answered-by-expert Expert Answer
Resistance of a conductor is directly proportional to temperature.
Reason :
With the increase in temperature, vibrational motion of the atoms of conductor increases.
Due to increase in vibration, probability of collision between atoms and electrons increases.
As a result, resistance of conductor increases.
