I am not sure how the configuration would look like if we add a voltage across these points. I have drawn out what I think it would look like after a potential is applied across Vab. My question is, is this drawing correct?? What about Vbc and Vac? This is question 26.5. And here is my attempt for (a) Once I figure out the configuration, I can easily add up the R_eq and find the I from that. But I need to make sure my configuration is correct!
