Equivalent resistance between two points on a circuit

Click For Summary
SUMMARY

The discussion focuses on calculating the equivalent resistance between two points in a symmetric electrical circuit. Participants suggest using symmetry arguments and converting star configurations (BC-OC-DC) into delta forms for simplification. The final equivalent resistance between points A and O is confirmed to be 7/15 Ohms, while the resistance between A and D is determined to be 8/15 Ohms. The conversation emphasizes the importance of identifying equipotential points and applying symmetry effectively to solve circuit problems.

@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
