We complete the solution of a circuit using the Mesh Current method. This video covers steps 4 and 5 where we solve the system of equations for mesh currents, and reveals the element current in each individual resistor.

The steps of the Mesh Current Method are,

  1. Identify the meshes (the open windows of a circuit). Draw and name mesh current arrows in each mesh, using a consistent direction.
  2. Solve the easy mesh currents, the ones that pass through a constant current source.
  3. Write Kirchhoff’s Voltage Law around each mesh.
  4. Solve the resulting system of equations to get the mesh currents.
  5. Find the element currents and voltages with Ohm’s Law.
