1. ### what is the magnitude of the current in the wire above the junction?

since the positive of both votage drops is common, this means that both currents I1 and I2 come fom I with the same versus and share , therefore : I = 6/2 + 10/5 = 3+2 = 5.0 A

8. ### help with this EMF question.?

I = (E1-E2)/(r1+r2+R) = (2-1)/(0.1+0.2+2.7) = 1/3 A V1 = E1-r1*I = 2-0.1/3 = 1.967 V V2 = E2-r2*I = 1-0.2/3 = 0.933 V
