Solving Electrical Circuits: V1 & V2 Equations

Click For Summary

Discussion Overview

The discussion revolves around solving equations for electrical circuits, specifically focusing on the V1 and V2 equations derived from z-parameters in a 2-port network. Participants are addressing a homework problem and exploring the application of course notes and definitions related to z-parameters.

Discussion Character

  • Homework-related, Technical explanation, Debate/contested

Main Points Raised

  • One participant presents equations for V1 and V2 based on given z-parameters.
  • Another participant questions whether a specific question was provided with the equations, emphasizing the need for showing work rather than confirming answers.
  • A participant mentions that the example differs from those taught in class, suggesting potential confusion.
  • Another participant expresses uncertainty about their approach and seeks validation on whether they are on the right track.
  • A later reply advises against making guesses and suggests using definitions of z-parameters to derive results confidently, referencing course materials and external sources like Wikipedia for clarity.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus. There are differing views on the adequacy of the provided equations and the necessity of showing work versus confirming answers.

Contextual Notes

There are indications of missing assumptions regarding the specific problem context and the definitions of z-parameters, which may affect the clarity of the discussion.

Homework Equations




3. The Attempt at a Solution

Z11 8 + 6
Z12 6
Z21 6
Z22 6

V1 = Z11 I1 + Z12 I2
V2 = Z21 I1 + Z22 I2

Was there a question to go with this?

We won't just confirm raw answers; you need to how your work.
 
I just follow course notes. The question is exactly as above.
 
The example above is slightly different than taught ones hence the question.

This is what I came across and that is where my attempt comes from. cheers. Am I on the right track?
 
Once again, we don't confirm guesses.

Rather than trying to extrapolate a guess from a given example I'd suggest using the definitions of the individual z-parameters. Your text or course notes should define them in terms of port currents and voltages. Barring that, Wikipedia does a reasonable job showing their definitions. With them you can find the parameters for a 2-port network and be confident in the results.

You probably won't have handy examples to work from on an exam ;)
