This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

This one can be solved with a series of wye-to-delta and delta-to-wye transformations. I haven't actually crunched the numbers, but below are the transformations I would use. Note that the color coding is just to show the changes from one step to another. Legs of the same color don't necessarily have the same resistance.
@Steven Chase sir i got the answer using this delta star one , but it gets complicated after each time we apply . Btw i have a hint which came with the problem , can i post ? then can u try by that method ?

@Steven Chase sir this was the hint : [img]https://i.postimg.cc/h4sWCmh5/23047a35975b524cd8674eeb5c6aa41b50d0f989-1-690x383.png[/img] i am not getting how they got AB as symmetry line. I cannt think that AB is symmtry line

@Steven Chase sir should i post that image in the actual problem as such i am not getting any option to let it be posted in comment section ? ( As such i have mentioned the link above , can u copy paste it Sir ? U will get the image )

I generally just start a new dummy problem or note, upload a picture to that, paste it into here, and then cancel the dummy problem. It's cumbersome, but it works.
@Steven Chase sir , how to do this problem as such i am mot getting any symmtry line also not any equipotential points here . ( Maybe there are equipotential points ) Btw answer is suppose to be 2 , Can u try this one ?

I'm not really convinced of the validity of the symmetry approach.
