Question

The resistivity (ρ) of semiconductor varies with temperature. Which of the following curve represents the correct behavior Image

G1 Physics · Accepted Answer

For a semiconductor, increasing temperature produces more charge carriers. Therefore conductivity increases and resistivity decreases with increasing temperature. So the ρ–T graph must show resistivity decreasing as temperature rises. Hence the curve in option C is correct.
