The discussion revolves around the application of wye-delta transformation in a circuit analysis problem involving resistors. Participants are exploring methods to find specific equivalent resistances (Rae, Rbf, Rah, Rcg, and Rbc) and discussing the potential use of transformations and circuit reduction techniques.
Participants have not reached a consensus on the necessity of the wye-delta transformation, as there are differing views on its applicability and the methods to be used for solving the problem.
The discussion does not clarify the specific circuit configuration or provide detailed assumptions regarding the connections between resistors, which may affect the applicability of the proposed methods.

Homework Equations
Am I going to use wye-delta transformation?
The Attempt at a Solution
I tried checking if I could use wye-delta transformation. There seems to be no parallel connections between the resistors. Please do help. Thank you
Hi anning, Welcome to Physics Forums.
You might use Δ-Y transformations for Rah [STRIKE]and Rbc[/STRIKE] (the others can be reduced via the usual serial/parallel reductions). You could also first reduce what you can and then stick a voltage source across the terminals in question and solve for the current using KCL, KVL, or other analysis methods. Then Ohm's Law yields R = V/I.
