Show graphically how electric resistance of a piece of Silicon or Germanium varies when its temperature is varied.

Explanation

To show graphically how the electric resistance of a piece of Silicon or Germanium varies with temperature, we can follow these steps:

### Step 1: Understand the Behavior of Semiconductors
Silicon and Germanium are semiconductors, which means their resistance behaves differently compared to conductors and insulators. As the temperature increases, the resistance of semiconductors decreases due to the increased thermal energy that allows more charge carriers (electrons and holes) to be available for conduction.

### Step 2: Set Up the Axes for the Graph
We will create a graph with:
- The x-axis representing Temperature (T) in degrees Celsius or Kelvin.
