Show on a graph, the variation of resistivity with temperature for a typical semiconductor.

Explanation

To show the variation of resistivity with temperature for a typical semiconductor, we can follow these steps:

### Step 1: Understand the relationship between resistivity and temperature
- The resistivity (\( \rho \)) of a semiconductor decreases as the temperature increases. This is due to the increase in the number of charge carriers (electrons and holes) available for conduction as temperature rises.

### Step 2: Recall the formula for resistivity
- The resistivity of a semiconductor can be expressed as:
\[
