1. The problem statement, all variables and given/known data Consider the following configuration. Given: EMF1=6 V EMF2 = 3 V R1 = 600 Ohm R3 = 100 Ohm 1. Calculate the current i1. 2. Calculate the current i3. 2. Relevant equations V=IR Kirchoff's circuit laws: 1. Sum of current into any node is zero. 2. Sum of voltages around any loop is zero. 3. The attempt at a solution I know that the potential at point A is 6 V because of the battery. I can't figure out how to calculate i1. I think I somehow have to use Kirchoff's rule, but I just don't know how. I tried to set up a voltage equation: EMF1 -i1R1 - i3R3 = 0. I don't know if that's right but it still has two unknowns. For i3, it seems like I have to know what i1 is to calculate it. Any help is appreciated!
