Ohm's Law, Resistivity & Temperature

Which of the following graph represents the temperature (T) dependence of resistivity ( $\rho$ ) of a semiconductor?

Show answer and solution

Answer: (b)

In a semiconductor, more charge carriers are created as $T$ rises, so $\rho$ falls.
The fall is roughly exponential: $\rho$ drops steeply at first, then levels off.
Graph B shows this decreasing curve.
So the answer is (b) B.
