I have 1 more problem for the mesh current method which I'm a little hesitant to ask for help for as it's my third post for circuit analysis problems, and I don't really have any work to show. I did try it, but I'd rather show a clean picture without equations that don't lead anywhere.
What I first did was the easy equations for loop ib and ic, but I know I won't get anywhere if I don't somehow relate the 10 mA source or loop ia in with them. The constraint. I don't want the answer given to me, if anyone knows, don't say, just hint, I'd really like the satisfaction of seeing the constraint.
10 mA flows in through R1 & R2, down towards the bottom. Whatever passes through R1 and R2 - 10 mA = 0. But how can I express "whatever passes through R1 and R2"? I was thinking about labeling the nodes, and doing (Va is top) Va/R1 + Va/R2 = 10 mA.... and then Va/R2 = ib....so
Va/R1 + ib = 10 mA......ib = 10 mA - Va/R1. But that's completely wrong cuz it's not Va, it's Va - the voltage in the middle.
I know it's a simple KVL equation, which I currently can't see. Anything I try just ends up saying ia = 10 mA, or something flat like that, which doesn't help. I want to say something like, 2ia = ib + ic...
