What is Supermesh and supernode?

The problem arises when the current source (independent or dependent) exists between two meshes. So, then to solve the circuit a supermesh is created by excluding the current source and any elements connected in series with it. Nodal analysis and supernode: In nodal analysis we use KCL.

How do you solve Supermesh?

Summary of Supermesh Analysis (Step by Step)

1. Evaluate if the circuit is a planer circuit.
2. Redraw the circuit if necessary and count the number of meshes in the circuit.
3. Label each of mesh currents in the circuit.
4. Form a supermesh if the circuit contains current sources by two meshes.

What is Supermesh analysis?

A supermesh occurs when a current source is contained between two essential meshes. The circuit is first treated as if the current source is not there. This will be an equation where the current source is equal to one of the mesh currents minus the other. The following is a simple example of dealing with a supermesh.

When can you use supernode?

In circuit theory, a supernode is a theoretical construct that can be used to solve a circuit. This is done by viewing a voltage source on a wire as a point source voltage in relation to other point voltages located at various nodes in the circuit, relative to a ground node assigned a zero or negative charge.

Which of the following are the properties of a Supermesh?

Note the following properties of a supermesh :

• The current source in the supermesh provides the constraint equation necessary to solve for the mesh currents.
• A supermesh has no current of its own.
• A supermesh requires the application of both KVL and KCL.

What is the difference between mesh and Supermesh?

This is a situation where two electrical closed loops (meshes) have a common current source between them. A supermesh occurs when a current source is contained between two essential meshes. This leads to one equation that incorporates two mesh currents.

How can you tell if there is a supernode?

The supernode is indicated by the region enclosed by the dotted line. This is possible because, if the total current leaving Node2 is zero (0) and the total current leaving Node3 is zero (0), the the total current leaving the combination is zero.
