2. Mesh Analysis(Loop Analysis)
Mesh Analysis is developed by applying KVL around meshes in
the circuit.
Loop (mesh) analysis results in a system of linear equations
which must be solved for unknown currents.
Reduces the number of required equations to the number of
Meshes
Can be done systematically with little thinking
As usual, be careful writing mesh equations-follow sign
convention.
3. Step of mesh analysis:
1. Identify the number of basic meshes.
2. Assign a current to each mesh.
3. Apply KVL around each loop to get an equation in terms
of the loop currents.
4. Solve the resulting system of linear equations.
4. Super MESH:
A supermesh forms when two meshes have a common current source (dependent or independent). Consider a circuit
as shown below in Figure1 in which the current source branch is common between meshes 1 and 2.
so remove the current source branch and supermesh forms as shown in Figure 2.

8. Mesh Current Method:
There are two meshes in the above circuit. The mesh currents I1 and I2 are
considered in clockwise direction. These mesh currents are shown in the following
figure.
