My questions:
1) If I want to compare the potential at a point, is it correct to say V at P = V at A and V at S = V at B?
2) There is potential difference between point A and B (which is the same as the emf of solar cell) so why no current flows from B to A or A to B?
3) If point S is moved to the right (towards Q), then potential difference across PS > emf of solar cell then current will flow through galvanometer. How to determine whether the current will flow from A to B or B to A? And I think PS and AB are parallel and in parallel connection the potential difference will be the same but VPS ≠ VAB, what am I missing here?
Thanks
