Hello everyone, 'im trying to figure out the potential difference between Va-Vb but i'm confused. here is the picture:

I figured out the current in battery 1, 2 , and 3.
In Figure 27-40, the resistances are R1 = 1 , R2 = 2.2 , and the ideal batteries have emfs 1 = 2.0 V, and 2 = 3 = 3 V;
Since Batter 2 and 3 have the bigger amount of engery wouldn't it overcome the direction that Battery 1 has? But then current would be going from negative to positve?
