1. The problem statement, all variables and given/known data the problem is a circuit analysis. I can try to make the circuit but the image i created shows all the resistors and voltage sources. imgurl Find i,v,is,vs 2. Relevant equations [itex]\sum[/itex]loop vi=0 [itex]\sum[/itex]node ij=0 3. The attempt at a solution I can not make a voltage loop as of yet. That would be my first attempt. Each node that I make an equation for results in more variables than what I have equations for. I am stuck on a very fundamental level here I think.
