Question
### Diode I-V Characteristic Curve

#### Graph Description:

The graph illustrates the current-voltage (I-V) characteristic curve of a certain diode. It displays the relationship between the diode current (\(I_d\)) in milliamperes (mA) and the diode voltage (\(V_d\)) in volts (V).

- **X-Axis (Vd - Volts):** Ranges from -2.0 V to 2.0 V.
- **Y-Axis (Id - mA):** Ranges from -4.0 mA to 6.0 mA.

The curve shows that as the diode voltage (\(V_d\)) increases from negative to positive, the diode current (\(I_d\)) changes accordingly. The diode exhibits a typical forward-biased exponential increase in current beyond a certain threshold.

### Circuit Configurations:

Below the graph, three different diode circuits are depicted, labeled (A), (B), and (C). Each circuit consists of a voltage source, a resistor, and a diode. You need to draw and label the load line for each circuit on the plot in order to obtain the diode voltage and current.

#### Circuit Descriptions:

- **Circuit (A):**
  - Voltage source: 1.5 V
  - Resistor: 500 Ω

- **Circuit (B):**
  - Voltage source: 1.5 V
  - Resistor: 500 Ω

- **Circuit (C):**
  - Voltage source: 4 V
  - Resistors: 1 kΩ

### Task:

For each circuit configuration, determine the appropriate load line and mark it on the graph to find the intersection point, which indicates the operating point of the diode. This will help in analyzing the diode's behavior in different circuit setups.
