Above is a simple circuit. It has a voltage of 9V between the two terminals. I have drawn red lines which look like vectors, indicating how the current will flow. From the above diagram, I have a few questions:
When I talk about potential difference along a path, I'm referring to the potential of the vectors tip minus the potential of the vectors tail.
Can someone tell me if the potential difference is 0, increases, or decreases (even if by very little, a negligible amount) as the current flows along ABCDE?
If I were to guess, I would say that
Along A, the potential difference decreases. Along B, is 0. Along C, it decreases. Along D, it is 0. And along E, it also decreases.
