## Supermesh Analysis Solved Problems Pdf 40: A Resource for Circuit Analysis Students and Professionals

Supermesh analysis is a method of solving complex electric circuits that have two or more meshes with a current source as a common element. It is a variation of mesh analysis, which uses Kirchhoff's voltage law to create a system of equations for the mesh currents. Supermesh analysis reduces the number of equations by combining the meshes that share a current source into a single supermesh.

In this article, we will introduce you to the concept and steps of supermesh analysis, and provide you with a link to download the pdf file that contains the problems and solutions.

## What is Supermesh Analysis and How to Apply it?

Supermesh analysis is based on the following principles:

• A planar circuit is one that can be drawn on a flat surface without any wires crossing each other.

• A mesh is a closed loop of branches that does not contain any other loops within it.

• A mesh current is an assumed current that flows around a mesh in a clockwise direction.

• A current source is an element that provides a constant current regardless of the voltage across it.

• A supermesh is a combination of two or more meshes that have a current source as a common element.

The steps of applying supermesh analysis are:

• Identify all the meshes and mesh currents in the circuit. Assign clockwise directions to all mesh currents.

• Identify all the supermeshes and their associated current sources. Do not write equations for the supermeshes yet.

• Write Kirchhoff's voltage law equations for each mesh that is not part of a supermesh. Use Ohm's law to express the voltages in terms of the mesh currents.

• Write an equation relating the current source and the mesh currents for each supermesh. Use the fact that the current source equals the difference between the mesh currents that share it.

• Solve the system of equations for the unknown mesh currents using any suitable method, such as substitution, elimination, matrix inversion, or Cramer's rule.

• Use the mesh currents to find any other quantities of interest, such as branch currents, voltages, powers, etc.

## What are the Applications and Advantages of Supermesh Analysis?

Supermesh analysis is a useful technique for solving electric circuits that have multiple meshes with current sources. It can be applied to any planar circuit, which is a circuit that can be drawn on a flat surface without any wires crossing each other. Planar circuits are common in many practical applications, such as printed circuit boards, integrated circuits, and electronic devices.

Some of the applications and advantages of supermesh analysis are:

• It can handle complex multi-source circuits with resistors, capacitors, inductors, and dependent or independent sources.

• It can reduce the number of equations to solve by combining the meshes that share a current source into a single supermesh.

• It can simplify the calculations by dealing with impedances rather than admittances when writing the system of equations.

• It can work with voltage sources, which tend to be convenient for many circuits, while nodal analysis requires current sources.

• It can check the answers obtained by other methods, such as nodal analysis or Thevenin's theorem, by comparing the mesh currents and branch currents.

Supermesh analysis is a powerful and efficient technique that can help you solve circuit problems faster and easier. It is also a good way to improve your understanding of Kirchhoff's laws and Ohm's law.

## What are the Examples and Exercises of Supermesh Analysis?

Supermesh analysis is a technique that can help you solve circuit problems faster and easier. However, it requires some practice and understanding to apply it correctly and efficiently. In this section, we will provide you with some examples and exercises of supermesh analysis that you can use to test your skills and knowledge.

### Example 1: Supermesh with Two Current Sources

Consider the circuit shown below, which has two current sources and four resistors. Find the voltage across R4 using supermesh analysis.

The solution is as follows:

• Identify the meshes and mesh currents in the circuit. There are three meshes, but we can combine the two meshes that share a current source into a single supermesh. We assign clockwise directions to all mesh currents, as shown below.

Write Kirchhoff's voltage law equations for each mesh that is not part of a supermesh. For mesh 1, we have:

$$E_1 = R_1 i_1 + R_2 (i_1 - i_2)$$

Write an equation relating the current source and the mesh currents for each supermesh. For the supermesh, we have:

$$i_2 - i_3 = I_s$$

Solve the system of equations for the unknown mesh currents using any suitable method. We can use matrix inversion to get:

$$\beginbmatrix i_1 \\ i_2 \\ i_3 \endbmatrix = \beginbmatrix R_1 + R_2 & -R_2 & 0 \\ -R_2 & R_2 + R_3 & -R_3 \\ 0 & 1 & -1 \endbmatrix^-1 \beginbmatrix E_1 \\ E_2 \\ I_s \endbmatrix$$

$$\beginbmatrix i_1 \\ i_2 \\ i_3 \endbmatrix = \frac1(R_1 + R_2)(R_2 + R_3) + R_2^2 \beginbmatrix (R_2 + R_3) E_1 + R_2 E_2 - R_2 I_s (R_1 + R_2) \\ -R_2 E_1 + (R_1 + R_3) E_2 - (R_1 + R_3) I_s \\ -R_3 E_1 - R_3 E_2 + (R_3 + R_s) I_s \endbmatrix$$

Use the mesh currents to find the voltage across R4. We have:

$$V_R4 = i_3 R4$$

### Exercise 1: Supermesh with Dependent Current Source

## What are the Tips and Tricks of Supermesh Analysis?

Supermesh analysis is a technique that can help you solve circuit problems faster and easier. However, it requires some tips and tricks to apply it correctly and efficiently. In this section, we will provide you with some tips and tricks of supermesh analysis that you can use to improve your skills and knowledge.

### Tip 1: Choose the Smallest Number of Meshes

When applying supermesh analysis, you should choose the smallest number of meshes that cover all the components in the circuit. This will reduce the number of equations to solve and make the calculations simpler. For example, in the circuit below, you can choose two meshes instead of three by combining the two meshes that share a current source into a single supermesh.

### Tip 2: Label the Mesh Currents and Voltage Polarities Clearly

When applying supermesh analysis, you should label the mesh currents and voltage polarities clearly on the circuit diagram. This will help you write the Kirchhoff's voltage law equations for each mesh and supermesh without confusion. You should assign clockwise directions to all mesh currents by convention, and use Ohm's law to express the voltages in terms of the mesh currents.

### Tip 3: Use Vector Addition for Current Sources

When applying supermesh analysis, you should use vector addition for current sources that are in series or parallel with each other. This will help you write the equation relating the current source and the mesh currents for each supermesh without confusion. You should use the sign convention that a positive current flows out of the positive terminal of a current source, and a negative current flows into the negative terminal of a current source.

### Tip 4: Use Matrix Inversion for Solving Equations

When applying supermesh analysis, you should use matrix inversion for solving the system of equations for the unknown mesh currents. This will help you solve the equations faster and easier than using other methods, such as substitution, elimination, or Cramer's rule. You should use a calculator or a software tool that can perform matrix operations, such as MATLAB or Excel.

When applying supermesh analysis, you should check your answers using other methods, such as nodal analysis or Thevenin's theorem. This will help you verify your results and avoid mistakes. You should compare the mesh currents and branch currents obtained by different methods and make sure they are consistent.
