Equivalent resistance between two points on a circuit

Click For Summary

Homework Help Overview

The discussion revolves around determining the equivalent resistance between two points in a circuit, utilizing symmetry considerations. Participants are exploring how to simplify the circuit based on its symmetrical properties.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the potential to simplify the circuit by splitting nodes and applying symmetry arguments. There are inquiries about the implications of these splits and how they affect current flow. Some suggest converting star configurations to delta forms as a means of simplification.

Discussion Status

The discussion is active, with various participants sharing their thoughts on symmetry and its application in the circuit analysis. Some have expressed uncertainty about the effectiveness of their approaches, while others are attempting to validate their reasoning through dialogue. There is no clear consensus, but several productive lines of inquiry are being explored.

Contextual Notes

Participants note that all provided options for the equivalent resistance may be incorrect, which raises questions about the assumptions made in the problem setup. There is also mention of the need for clarity on which points can be considered equipotential based on symmetry.

@TSny ,

I came across a similar problem (hope I am not wrong :smile: ). Please see the attached picture . I do not have the answer key . Could you please confirm whether you get 22/35 Ω as the answer .

Thank you
