Hello people, this time I request your help for a fairly easy question, but a crucial one for me. To be honest I wasn't full awake when my teacher in university was talking on this topic( :( ), so I don't know how to solve it. 1. The problem statement, all variables and given/known data Given on attachment. (Superior paint skills detected) 2. Relevant equations Eh, not sure if I really need to say that, but the currents that moves in and moves out from a junction must be equal. 3. The attempt at a solution I think I ve found the currents which batteries drive on the circuit. 50 V battery drives in 4.5 A, while 40V drives in 4.3 A.
