1. The problem statement, all variables and given/known data Use the mesh current method to solve for the power dissipated 2. Relevant equations v1+v2+..vn=0 i=v/R p=i*v 3. The attempt at a solution I was trying to solve the question using two equations, eq1) 20=4*i1+i1 eq2) -90=9*i2+6*i2 eq3)i2-i1=6A... So I obviously made a mistake since the 6A is doing nothing in my equations, and both equations 1 and 2 have no unknowns. Am I suppose to just use one equation, and use the super node as my second? How can I tell when I need to use only one equation?
