How do you handle a supermesh in mesh current analysis?

In mesh current analysis, a supermesh is a special case that occurs when a current source is present between two meshes (loops) in a circuit. Supermeshes are formed by combining two or more individual meshes that share a current source. When dealing with supermeshes, you need to follow specific rules to properly analyze the circuit. Here's a step-by-step guide on how to handle a supermesh:

Identify the supermesh: Look for meshes in the circuit that share a current source (dependent or independent).

Assign mesh currents: Assign mesh currents to all individual meshes in the circuit, including the supermesh. Mesh currents are arbitrary clockwise currents assigned to each loop in the circuit. Choose one direction (clockwise or counterclockwise) and stick with it throughout the analysis.

Define the supermesh current: For the supermesh, you cannot directly apply Kirchhoff's voltage law (KVL) because it includes a current source. Instead, you should define the supermesh current as the algebraic sum of the individual mesh currents that form the supermesh. If both mesh currents flow in the same direction through the shared current source, their sum is the supermesh current. If they flow in opposite directions, their difference is the supermesh current.

Apply KVL around individual meshes: Apply Kirchhoff's voltage law (KVL) to each of the individual meshes as you normally would. Write the equations using Ohm's law (V = I * R) for resistors and the appropriate formula for other circuit elements (e.g., voltage sources).

Account for the current source: When you encounter the current source that is part of the supermesh, incorporate it into the appropriate KVL equation. Use the supermesh current (the algebraic sum of the individual mesh currents) as needed.

Solve the equations: Solve the resulting system of equations for the mesh currents, including the supermesh current. You can use techniques like substitution or matrix methods (e.g., Cramer's rule or Gaussian elimination) to solve the equations.

Calculate other values: Once you have the mesh currents (including the supermesh current), you can use them to determine various circuit parameters, such as voltage drops across resistors or power dissipation.

By following these steps, you can effectively handle a supermesh in mesh current analysis and obtain the necessary currents and voltages in the circuit. Remember to be consistent with your current directions and apply the proper sign conventions when dealing with the supermesh current to get accurate results.
