# DC Circuit Equivalent Resistance Problem

Hello guys,
My teacher gave me a question regarding calculation of equivalent resistance, trying to solve which I’m losing my sanity. I feel a bit ashamed because this is my first post and I’m using it to ask a doubt, a little selfish of me. But it’s kind of urgent so I don’t really have a choice. Now I’ve read the rules and I know I’m going a little out of the line, because in order to show the circuit I’m going to have to attach an image, and also that I have made numerous attempts at the solution and all of them are wrong, so I don’t know if I should attach them or not. Should I attach any one of them? The values of all the resistors in the circuit is R, and we have to find RAB and RAC in the question. I do not know the answer for RAC, but the answer for RAB is (3/2)R, or 1.5R. If anyone can show me how can I simplify the circuit in order to get the value of RAB as 1.5R, I will be EXTREMELY grateful! I just need to know the correct way of how to simplify this circuit, because I’ve tried many different approaches, all resulting in different and incorrect answers. :confused: Thanks for reading, and I sincerely apologize for not fully complying to the rules here, I would be grateful if anyone could point out how I can follow them and still ask my question properly. Thanks đź™‚ I’ve attached the image of the circuit (Sorry for my horrible drawing skills) .
1. The problem statement, all variables and given/known data

Simplify the given circuit and obtain the values of RAB and RAC.

2. Relevant equations

None, I’ve attached the image of the circuit. The values of all the resistors in the circuit is R.

3. The attempt at a solution

All my attempts are wrong. Should I just attach any one of them? Help me out here please!
