By increasing the temperature, the specific resistance of a conductor and a semiconductor.

Options

A. increases for both
B. decreases for both
C. increases, decreases
D. decreases, increases

Answer

C

Explanation

increases, decreases
As the temperature of conductor increases, the random motion of ions increases so the motion of electrons becomes more constrained, so the specific resistance increases. When increasing the temperature of covalent bond breaks and form a larger number of holes electron hence resistance decreases.
