Question:

Identify the graph from the following showing the temperature dependence of resistivity for a typical semiconductor?

Options:

Correct Answer:

Explanation:

The correct answer is Option (3)

 

The Resistivity $(ρ)$ is,

$ρ∝\frac{1}{T}$

∴ → At low temperature, resistivity is high.

→ As the temperature increase, resistivity decreases
