**Title: Analytical Exploration of Kirchhoff's Circuit Rules**

**Figure 1 Overview:**

The diagram illustrates a circuit containing two voltage sources (\(\varepsilon_1\) and \(\varepsilon_2\)), three resistors (\(R_1\), \(R_2\), \(R_3\)), and three currents (\(I_1\), \(I_2\), \(I_3\)). The circuit is designed as two loops with junctions marked, indicating the directional flow of electrical currents.

**Graph/Diagram Explanation:**

- **Components:** The circuit features two loops. Loop 1 contains \(\varepsilon_1\), \(R_1\), and \(R_2\). Loop 2 includes \(\varepsilon_2\), \(R_1\), and \(R_3\).
- **Current Directions:** Currents (\(I_1\), \(I_2\), \(I_3\)) flow through various branches with specified directions interacting with resistors and batteries.

**Section 1: Kirchhoff's Rules Application**

**Equations from the Circuit:**

**(a):**
- \(-I_2R_2 - \varepsilon_1 + I_1R_1 - \varepsilon_2 = 0\)  
- \(\varepsilon_2 - I_1R_1 - I_3R_3 = 0\)  
- \(I_3 = I_1 + I_2\)  

(True, False options are provided for checking theoretical assumptions.)

**(b): Calculation of Currents:**
- \(I_1 = \frac{\varepsilon_1R_3 + \varepsilon_2R_2 + \varepsilon_2R_2}{R_1R_2 + R_2R_3 + R_3R_1}\)  
- \(I_2 = \frac{-\varepsilon_1R_3 + \varepsilon_2R_3 + \varepsilon_2R_1}{R_1R_2 + R_2R_3 + R_3R_1}\)  
-  \(I_3 = \frac{\varepsilon_2R_2 + \varepsilon_2R_3}{R_1R_2 + R_2R_3 + R_3R
