Wow! You're starting to make up your own exercises! Cool!So now I want to find Vcd
Vc -> 0
(I can do that, right? Set Vc as my zero point, since it makes things easier)
Vcd = I2 x 0.5 - I3 x 4 = 8.615 x 0.5 - 2.077 x 4 = -4 V
Well, let's see....
You followed the wire down and back up.
Can you also follow the wire up and then back down?
(As for setting Vc to zero. I guess that's fine, although I wouldn't write it down.)
