**Circuit Analysis Description**

This image depicts an electrical circuit comprising various components arranged in a loop. Here's a detailed explanation:

1. **Voltage Source**: 
   - A 75 V independent voltage source is positioned on the left, supplying power to the circuit.

2. **Resistors**: 
   - Three resistors are present:
     - A 2 Ω resistor is connected in series immediately after the 75 V source.
     - A 5 Ω resistor is connected in parallel with a dependent current source, denoted as \( v_1 \).
     - A 1 Ω resistor is placed in series following the parallel network.

3. **Current Source**:
   - A 10 A independent current source is situated at the top of the circuit, directing current counterclockwise.

4. **Dependent Source**:
   - A voltage-controlled current source is depicted on the right. It is indicated as 0.4\( v_1 \) and is dependent on the voltage across the 5 Ω resistor.

5. **Current and Voltage Notations**:
   - The loop current \( i_a \) is shown in red, flowing counterclockwise through the circuit.
   - The voltage across the 5 Ω resistor is labeled as \( v_1 \), with positive and negative terminals clearly marked.

This circuit can serve as a practical example for analyzing loops using techniques such as mesh analysis, where the goal is to determine unknown currents and voltages throughout the circuit components.
