**Figure 3-17: Applying Thevenin’s Theorem**

This figure demonstrates the application of Thevenin’s Theorem through three circuit diagrams: (a), (b), and (c).

**(a) Original Circuit:**
- The circuit is powered by an 80 V voltage source.
- Resistors are arranged in a combination of series and parallel:
  - Two 2 kΩ resistors in series with a 1 kΩ resistor across them.
  - Another three 2 kΩ resistors and 1 kΩ resistor in series.
  - The overall arrangement forms two main paths from the voltage source to the output terminals A and B.
- Thevenin voltage (Vth) is represented at the terminals A and B after they are open-circuited.

**(b) Simplified Thevenin Equivalent Without Load:**
- This diagram shows a Thevenin equivalent circuit with a 5 V voltage source.
- A single 1 kΩ resistor is placed in series between terminals A and B.
- There is no load connected in this configuration.

**(c) Thevenin Equivalent with Load:**
- The diagram includes the same 5 V voltage source and 1 kΩ resistor from part (b).
- However, a load resistor (R_L) of 3 kΩ is connected between terminals A and B.
- The current flow (I) through the circuit is indicated.

This illustration helps visualize the process of replacing a complex circuit with a simplified Thevenin equivalent circuit to analyze load behavior.
