Trying to understand this problem. Get most of it but the R4 stub and the opposing voltages are puzzling me. So, I put it into LTS and checked all the voltages which are annotated onto the LTS schematic. And my calculations agree.
Analyzed and have no problem with the V1 to V2 part of the circuit. The R4 part is where I'm a bit confused. Just sitting there with R4 unattached there is 0V dropped across it because it is floating. I think I understand that. And when I measure the out tag I get the 46.33V that I see at V1 because there is no voltage dropped across R4? BUT! Am I not measuring that out tag voltage to ground? And IF I am measuring it ground that would mean that I am dropping all of the 46.33V across R4 even though I measure 0V across it floating and 46.33V at the out tag when it is floating? How can it be both 0V and 46.33V? In fact, I only have 20V from the 50V E1 being opposed by the 30V E2! Yes I understand that I am measuring from the 50V E1 to ground but that 50V is being opposed by the 30V from E2.
