1. The problem statement, all variables and given/known data Introductory Circuit Analysis 12th edt Boylestad, page 255, Example 7.8 This is not homework, I am just reading the text book. It says: "It is now obvious that: V2 = -E1 = -6V" Is it obvious? :S 3. The attempt at a solution I don't really understand that, so I created the circuit in multisim and hooked up three voltmeters, and they all read -6. I understand XMM1 reading -6, and XMM2 is kinda measuring the same points, I can understand that. But XMM3? -6? Seems.. strange If I visualize XMM3 measuring everything to the LEFT, the voltage is -6. Alright, but if I visualize it measuring everything from the right, surely it should be relevant that there is an 18V source there. Why is there no contribution in these three measurements from V2, the 18V source?
