The circuit shown appears to be a combination of resistors connected in series and parallel, along with a current source and a voltage source. The goal is to find the current \(i\) given that \(R = 7 \ \Omega\).

### Step-by-Step Solution Outline:

1. **Identify series and parallel resistors**:
   - The resistors are arranged in a mixed configuration (series and parallel).

2. **Simplify the circuit**:
   - Start with simplifying the 4 Ω and 2 Ω resistors in parallel:
     \[
     \text{Equivalent Resistance} = \left(\frac{1}{4} + \frac{1}{2}\right)^{-1} = \frac{4}{3} \ \Omega
     \]

   - Similarly, simplify the 8 Ω and 6 Ω resistors in parallel:
     \[
     \text{Equivalent Resistance} = \left(\frac{1}{8} + \frac{1}{6}\right)^{-1} = \frac{24}{7} \ \Omega
     \]

3. **Add the current source path**:
   - The 4A current source branches between the resistor combination, which affects the overall analysis.

4. **Solve for the total current**:
   - Use Kirchhoff's Current Law (KCL) or Kirchhoff's Voltage Law (KVL) and Ohm's law across the entire circuit to solve for the current \(i\).
