# Module 4 Mesh Analysis

• VOLTAGE SOURCE
• CURRENT SOURCE
• AMMETER

### Overview

A mesh is a special case of a loop. A mesh is a loop that does not contain any other loops within it. The current flowing in a mesh is defined as mesh current. As a matter of convention, the mesh currents are assumed to flow in a mesh in the clockwise direction. Employ KVL around each mesh. Go around each mesh in the clockwise direction and sum the voltage rises and drops encountered in that particular mesh. Once the mesh currents are known, the branch voltages are found using Ohm’s law. If we have N meshes with N mesh currents, we can obtain N independent mesh equations.
1. Construct the circuit as shown.
2. Connect the ammeters as shown to measure the mesh currents and click on DC Analysis and run without any sweep settings.
Practically using ammeters the mesh currents can be obtained. Using mesh analysis as explained above, i.e. using KVL solve for the unknown current values. Verify the values obtained with the values obtained practically here.
