The image is a schematic of an electrical circuit. It consists of two voltage sources and three resistors arranged in a combination of series and parallel configurations. Here’s a detailed description:

1. **Voltage Sources**: 
   - There are two voltage sources labeled as \( \xi_1 \) and \( \xi_2 \).

2. **Resistors**:
   - Three resistors are present, labeled \( R_1 \), \( R_2 \), and \( R_3 \). 

3. **Current Flow**:
   - The current \( I_1 \) flows through resistor \( R_1 \).
   - The current \( I_2 \) flows through resistor \( R_2 \).
   - The current \( I_3 \) flows through resistor \( R_3 \).

4. **Circuit Configuration**:
   - The circuit comprises two branches:
     - The upper branch consists of voltage source \( \xi_1 \) in series with resistor \( R_1 \).
     - The lower branch consists of voltage source \( \xi_2 \) in series with resistors \( R_2 \) and \( R_3 \).
   - \( R_2 \) and \( R_3 \) are aligned such that the currents \( I_2 \) and \( I_3 \) oppose each other in direction.

This circuit diagram can be used to illustrate principles of circuit analysis, including the calculation of current distributions and potential differences across components using laws like Ohm's Law and Kirchhoff's Circuit Laws.
