### Circuit Analysis Problem

**Circuit Description:**

- **Inductor:** 40 mH positioned at the left top corner.
- **Current (`i₀`):** Flows leftward through the inductor.
- **Resistors:**
  - \( R_1 \) located on the left side.
  - \( R_2 \) placed vertically after the dependent voltage source.
  - \( R_3 \) horizontally near the switch.
  - \( R_4 \) in series with a 10 A current source on the right.
- **Dependent Voltage Source:** 
  - Denoted as \( aV \), where \( a = 0.7 \) A/V.
- **Independent Voltage Source:** 
  - \( 140 \) V located vertically after the switch.
- **Independent Current Source:** 10 A to the right side of the circuit.
- **Switch:**
  - Initially open, closes at \( t = 0 \).

**Given Values:**

- \( R_1 = 80 \, \Omega \)
- \( R_2 = 160 \, \Omega \)
- \( R_3 = 240 \, \Omega \)
- \( R_4 = 320 \, \Omega \)

**Objective:**

Determine the coefficients for the current \( i₀ = K_1 + K_2 e^{-K_3 t} \, A \).

**Coefficients to Determine:**

- \( K_1 = \)
- \( K_2 = \)
- \( K_3 = \)

**Instructions:**

Using the given circuit values and the relationship provided for \( i₀ \), solve for the coefficients \( K_1 \), \( K_2 \), and \( K_3 \) by applying appropriate circuit analysis techniques, such as Kirchhoff’s laws, node-voltage analysis, or mesh-current analysis.

### Diagram Explanation:

- **Positioning:** The circuit components are laid out from left to right, with the inductance and switch prominently marked.
- **Flow:** Current \( i₀ \) flows counterclockwise around the loop when the switch closes.
- **Dependency:** The voltage across the dependent source is multiplied by a factor \( a \).

### Analyze & Solve:

- Break down each loop and apply laws of circuits for thorough analysis.
- Use the given resistance values, current, and voltage sources to formulate equations
