Better way to solve this circuit?

  • #1
Hi!

I was having a hard time doing problem 9.2.3b in Boylestad's book "Introductory Circuit Analysis", and was about to ask here when I finally got the right answer! But I have a feeling I did this the hard way, and that there's a quicker and more elegant solution. If you have suggestions to how this could be done (using superposition) a lot faster, please tell me. I've attached my solution...

(this is *not* homework. I'm just really unsure about the way I solved this and don't want to get any bad habits)

Oh, better add that the goal is to find the current through R1.
