Got it. Thank you!

Thank you for replying. Of course VAB = 0, but the problem is how to express it using E1, E2, I and r (it's a question from an exam). My dilemma is if it's 2Ir + E1 - E2, or -2Ir + E1 - E2. There is no reference about the direction of the current I, just that "the current goes through the...

TL;DR: simple problem with voltages I have a very simple problem with voltages, and I think that the answer in my book is wrong. In the attached image, what's the voltage between A and B, expressed with E1, E2, I and r? (The answer in the book is 2Ir + E1 - E2, but I think that is should be...
