1. The problem statement, all variables and given/known data See attached image. 2. Relevant equations 3. The attempt at a solution I cannot find any resistors in parallel or series in the circuit. I am confused by the lone branch going from the 10kOhm resistor back to the other end of the same resistor. How do I deal with that? I tried specifying nodes, Node A being connected to the 10kOhm, 20kOhm and maybe the 30kOhm and 80kOhm resistors? Node B connected to the 8kOhm and the 80kOhm resistors. Node C connected to the 20kOhm, 30kOhm and the 8kOhm resistors. This way I get 20kOhm and the 30kOhm resistors in parallel, but then I am confused about how to deal with the 10kOhm resistor. Is it in series? Parallel? with the other 2?
