Hey, I'm having a bit of difficulty with this specific circuit theory problem... We understand the basics, Ohm's law, Kirchoff's voltage and current laws, voltage and current division... I'm just confused about what to do with this problem: Find the value of Vx in the circuit below such that the power supplied by the 5-A source is 60W. I mean, I figure I'd start with the 5A current source... P=IV, so the potential over that current source would be 12v? I don't know, I'm really confused. The shape of this thing has me confused as well, what's in parallel with what and what's in series? I'm completely stumped. Any pointers on how to go about this problem?
