1. Number of equations needed is equal to the number of meshes (loops) in the network. 2. Mesh analysis is used for planar networks only, where the network is drawn with no crossing branches. 3. Assign clockwise mesh current in each mesh. A mesh current exists only in the perimeter of a mesh. In some parts of the mesh, the mesh current may be the same as the branch current. 4. Generate the Mesh equations by summing voltages around each mesh (using KVL). Voltages are to be considered positive unless a voltage source exists in the mesh (then you use the polarity of the voltage to determine the sign). Where two meshes have a common branch, a net current (one mesh current minus the other) must be used to express voltage in that branch.
