Discussion Overview

The discussion revolves around finding the Thevenin equivalent circuit between nodes A and B, and also between nodes C and D. Participants are addressing a homework problem that involves circuit analysis using Thevenin's theorem, including the application of relevant equations and methods.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant expresses difficulty in starting the analysis for the Thevenin equivalent between nodes A and B, despite having worked through part of the problem for nodes C and D.
  • The participant provides equations related to the circuit analysis, including Voc, Isc, and Rth, but does not complete the analysis for nodes A and B.
  • Another participant requests a larger version of the attached image for better readability, indicating that the current size is too small and blurry.
  • A different participant suggests a resource that may assist in solving the problem and offers to clarify further if needed.

Areas of Agreement / Disagreement

The discussion does not show consensus, as participants are at different stages of understanding and problem-solving. There is a request for clarification and assistance, indicating that some aspects remain unresolved.

Contextual Notes

The analysis appears to depend on the clarity of the circuit image, which has been noted as an issue by participants. There may be assumptions regarding the circuit elements and their relationships that are not fully articulated.

Who May Find This Useful

Students or individuals studying circuit analysis, particularly those interested in Thevenin's theorem and its applications in electrical engineering.

Homework Statement


For the circuit shown: Find the Thev Eq between nodes A and B and then for nodes C and D.
I worked the second half of the equation but am stuck on how to begin the analysis for the opposite end of the circuit. I have attatched the image as well as posting it as I am having some issues with this terminal.

Homework Equations


Voc=Isc*Rth
KVL
KCL


The Attempt at a Solution

Between C and D:
ix+Bix=Voc/Ro
Voc=Ro[ix+Bix]
Isc= ix + Bix
Rth=Ro

Can you make the image bigger? It's too small to be readable and gets too blurry if zoomed.
 
Sorry.

I believe http://www.scribd.com/doc/454419/Class-3-Thevenins-and-Nortons-Theorem is of use in this problem. If you still have problems, I'll try to clarify things.

And the picture is readable now, thank you.
