**Figure 18-3: Circuit Diagram**

The diagram shows a circuit with the following components and paths:

- **Voltage Sources**: Two voltage sources labeled \( V_1 \) and \( V_2 \).
- **Currents**: Three different current paths labeled \( I_1 \), \( I_2 \), and \( I_3 \).
- **Resistors**: Three resistors labeled \( R_1 \), \( R_2 \), and \( R_3 \).

**Equation Options for Verification:**

In Fig. 18-3, which of the following equations is true?

A) \( V_1 + I_1 R_1 - I_2 R_2 - V_2 - I_3 R_4 = 0 \)

B) \( V_1 - I_1 R_1 - I_2 R_2 + V_2 - I_2 R_3 = 0 \)

C) \( V_1 - I_1 R_1 + I_2 R_2 - V_2 + I_2 R_3 = 0 \)

D) \( V_1 + I_1 R_1 + I_2 R_2 + V_2 + I_2 R_3 = 0 \) 

These equations represent potential applications of Kirchhoff's voltage law to the circuit. To solve, apply the law which states that the sum of voltages around any closed loop in a circuit must equal zero.
