A mesh is defined as a loop which does not contain any other loop within it. Mesh analysis is applicable only for planar networks. A network is said to be planar if it can be drawn on a plane surface without crossovers. If the network has large no of voltage sources, mesh analysis is very useful. This analysis consists of writing mesh equations by Kirchhoff’s voltage law in terms of unknown mesh currents.
Steps:
• Identify the mesh, assign a direction and a current.
• Assign polarities for voltage across the branches.
• Apply KVL around the mesh and use Ohm’s law to express the branch voltages in terms of unknown mesh currents and resistance.
• Solve the simultaneous equations for unknown mesh currents.
