SUMMARY

The discussion focuses on calculating the effective resistance between points A and B in a hexagonal circuit configuration. The star-delta transformation method was employed to convert upper and lower delta connections into Y configurations for simplification. Participants emphasized the importance of recognizing shorted points M, N, and P to simplify the circuit further, ultimately leading to a straightforward solution. The consensus is that the problem, while initially complex, can be resolved with basic circuit analysis techniques.

Homework Statement


Find the effective resistance between the points A and B.


The Attempt at a Solution



The circuit is a hexagon as shown in the image.
I used star-delta method to convert upper and lower deltas respectively into Ys and then did some simplification. However, I'm stuck up at one place. Refer the two figures.
Please help.

I think you over-think it. Notice that the circuit is shorted at 3 points M, N and P. Simplify the circuit and it comes down to a simple problem :biggrin:
