1. The problem statement, all variables and given/known data See attached image. I'm having trouble applying the concept of potential difference in a circuit. Vb-Va=? Va-Vb=? 2. Relevant equations Vab=Vb-Va 3. The attempt at a solution The overall voltage is 5V-2V=3V. The direction of the current is defined by the higher voltage batter (i.e. ccw). Because current is defined as direction of positive charge flow, Vb-Va=-3V Va-Vb=+3V Thus A is at a higher potential. Is my reasoning correct?
