The major difference between a pure semiconductor and a pure metal is that
A. metals are harder than semiconductor B. while resistance of metals decrease with temperature , the reverse is the case for semiconductor C. the resistance of metals increases with temperature, while for semiconductors, it is the reverse D. metals have forbidden gaps while semiconductors have not
Correct Answer: C
Explanation
Experiment shows that increase in temperature increases the resistance of a pure metal but decreases the resistance of pure semiconductor
