Question 191: Semiconductors and Logic Gates

Question

A piece of copper and another of germanium are cooled  from room temperature to $$77K,$$ the resistance of

Accepted Answer

Copper is a conductor,  so its resistance decreases on decreasing temperature as thermal agitation decreases; whereas germanium is semiconductor therefore on decreasing temperature resistance increases.

Answer
