Tardigrade Admin · Accepted Answer

Due to Temperature increase number of free electron increase and its amount goes larger then they start to resist motion of each other therefore Resistance of the conductor will increase (Graph-2) For Semiconductor: Number of free electron is very less. Due to temperature increase, number of free electron increase that electron act as a carrier therefore resistance of the conductor decrease.
