  9. Example 4.5

  10. Step 1 # of essential branch: 6 # of essential nodes: 4 # of equations: 6-(4-1)=3

  11. Step 2 See in the handout.

  12. Use Mathematica to Solve Equations Format: Solve[{equations separated by a comma},{list of unknowns}] To solve an equation: Evaluation→Evaluate Cells

  13. Figure 4.25 A branch includes a current source!

  14. Solve Using Mathematica

  15. Supermesh Mentally remove the current source from the circuit by avoiding the branch when writing the mesh current equations.
