ok i kind of see how you get that but that's not my problem my problem is finding which currents to use where

Thanks for the reassurance but by the way it wasnt neative

What is I5 I think its I3-I4+I2+I1 but not surehow to add em up any tips? thanks

Cant quite get this one. What I think is that I3 and I1 add together to get I2 and I found this equation V1+v2=E1-E2 and V3+V2=E3-E2 and I was substituting IR in for all the V's and I3+I1 where I2 comes in and making two equaitons and solving but no dice any tips? Thanks. _________/\R3\/l l...
