Remember that the current coming into a junction equals the current coming out of the junction. Also bear in mind that voltage is basically a height difference between two points. 1) If you measure the potential across two batteries and find that V1 = 1.3V and V2 = 1.4V, then you measure the potential between the negative ends of battery 1 and positive end of battery 2 and get V12-+ = -0.1 and the potential between the positive ends of...
