1. The problem statement, all variables and given/known data Find Rab https://sphotos-a.xx.fbcdn.net/hphotos-ash4/199915_496321627054024_1130826860_n.jpg [Broken] 2. Relevant equations Req = R1R2 / R1+ R2 3. The attempt at a solution bottom 2Ω resistors in series ---> Req1 = 4Ω top right 12 and 4 Ω in parallel ---> Req2 = 3Ω this 3Ω and the left top 6Ω are in parallel ---> Req3 = 2Ω 2 resistors of 4Ω bottom left are in parallel -->Req4 = 2Ω Req4 and Req3 are in series --->Req5 = 4Ω Req5 and Req1 are in parallel ----> Req6 = 2Ω Rab = 3Ω + 2Ω = 5Ω please let me know if I have gotten the correct answer. Thanks for your time.
