Discussion Overview

The discussion revolves around a supernode problem in circuit analysis, specifically focusing on the application of node voltage and mesh current methods. Participants seek assistance with formulating equations and understanding the relationships between voltages in the circuit.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses confusion about where to place voltage variables (V's) and how to approach the problem.
  • Another participant suggests studying a resource on node voltage and mesh current to better understand the problem.
  • A participant shares their progress with equations but questions the role of a current variable (i0) in their analysis.
  • There is a suggestion that the participant is using KCL node equations instead of KVL mesh equations, prompting a recommendation to identify meshes and write KVL equations.
  • One participant acknowledges the equations provided by another and suggests solving for V1 to find Io.

Areas of Agreement / Disagreement

Participants generally agree on the need to use mesh analysis but there is some confusion regarding the correct approach and the equations being used. The discussion remains unresolved as participants continue to seek clarification and assistance.

Contextual Notes

There are limitations in the clarity of the circuit diagrams shared, and assumptions about the methods being applied are not fully articulated. The discussion reflects varying levels of understanding among participants.

You can start by studying this: http://www.calvin.edu/~svleest/circuitExamples/NodeVoltageMeshCurrent/
This should enable you to give your problem a try and ask more specific questions.

I have a hard time understanding what I am doing here but that is what i got so far.

V1-v2=8
[(V1-4)/6]+(v1/12)+(v2/12)-2=0

Where does i0 come into place?

:confused:
The problem states that you should use the mesh analysis method. It looks like you're trying to do some sort of KCL node equations instead.

Draw the circuit, identify the meshes (loops), and "walk around" the meshes writing down the KVL mesh equations as you go. What do you get for the two equations?

That was the wrong picture i put up the first time,

The correct one is the one on my most recent post:

Ah. I see.

Well, it looks as though you've got correct equations. Solve for V1 and then you can determine Io.
