Week 6: Methods of Analysis(Mesh Method)

                           MESH CURRENT METHOD

The mesh current method

 -uses the mesh currents as the circuit variables.

STEPS:

1. Identify all of the individual meshes in the circuit.
2. Assign a mesh current to each mesh.
3. Identify meshes in which the current is known because there is a
current source in an outside branch of the mesh.
4. Assign voltages to all of the elements in the meshes with unknown
currents.
5. Use KVL around each mesh to write loop equation.
6. Use Ohm’s law to write the resistor voltages in terms of the mesh
currents.
7. Insert the voltage expressions into the KVL equations to arrive at a
set of mesh current equations. If there are n unknown currents,
there should be n equations relating them.
8. Solve the system of equations to find the mesh currents
