Homework Statement
Find Vx, as the 5A current source provides 50W to the circuit.
Homework Equations
##P = V.I##
##U = R.I##
The Attempt at a Solution
[/B]
At first, as 5A current source provides 50W, by ##p=vi## there should be 10v through it. Then, i applied KVL and found four equations including Vx:
##2i1-2i2=5##
##-2i1+5i2-2i3-i4=0##
##i3=-5A##
##-i2+3i4+Vx=0##
So, if solving this is the right way, i need one more equation, probably related to the path from Vx to the current source, but I'm not sure how to do this.
I guess it could be: ##Vx+2i4+(i1-i4)-i3=0##
Is it right? I mean, probably there's a better way to solve this question, but i couldn't with superposition or source transformation.
P.S. I don't have the answer
