Question
The image presents an output characteristic plot for an NMOS transistor. 

### Graph Description:
- **Axes**: 
  - The y-axis represents the **Drain current (I<sub>D</sub>)** in microamperes (µA), ranging from 0 to 800 µA.
  - The x-axis represents the **Drain-source voltage (V<sub>DS</sub>)** in volts (V), ranging from 0 to 6 V.

- **Curves**:
  - Several curves are plotted on the graph, each corresponding to a different **Gate-source voltage (V<sub>GS</sub>)**. The values are labeled as 2 V, 3 V, 4 V, and 5 V.
  - As V<sub>GS</sub> increases, the curves indicate higher drain current for the same V<sub>DS</sub>.
