Question
Consider the circuit in Figure 21.56, and suppose that the emfs are unknown and the currents are given to be $I_1 = 5.00 \textrm{ A}$ , $I_2 = 3.0 \textrm{ A}$ , and $I_3 = -2.00 \textrm{ A}$. (a) Could you find the emfs? (b) What is wrong with the assumptions?

1. No, since $I_1 \neq I_2 + I_3$
