I would like some help with solving this mesh circuit.

 

**Mesh Analysis (Super Mesh)**

1. **Assign mesh currents**  
   - Start by defining mesh currents for each loop in the circuit.

2. **“Remove” the super mesh**  
   - Identify and temporarily ignore the branch with the current source to form the super mesh.

3. **Apply KVL (Kirchhoff's Voltage Law)**  
   - Write KVL equations for the super mesh, considering the voltage contributions from resistors and other elements.

4. **Solve**  
   - Use the KVL equations to solve for the mesh currents.

**Circuit Diagram Explanation:**

- The circuit consists of a network of resistors and sources.
- A 30V voltage source is connected in series with a 2Ω resistor.
- There is a 4Ω resistor at the top left connected with an 8Ω resistor in series on the right side.
- The top-right corner contains a current source supplying 4A upwards.
- The bottom branch includes a 3Ω and a 1Ω resistor in series, placed between the branches defined by the other elements.
- A 6Ω resistor is parallel to the 3Ω and 1Ω series combination.
- The circuit forms an interconnected loop suitable for mesh analysis using the concept of a super mesh because it includes a current source that affects multiple meshes.
