SOLVED... I DON'T KNOW HOW TO DELETE THE POST. 1. The problem statement, all variables and given/known data Find the power delivered by a source (Is or Vs) connected between terminals a and b, after you've found the V and R Thevenin across those terminals. 2. Relevant equations P=IV Is=given Vth=found Zth=found The problem hints that I need to find the other response, but I don't know what they mean by that. 3. The attempt at a solution Vth*Is+Is^2*Rth IS WHAT I WAS LOOKING FOR. THANKS ANYWAYS. I assumed that for a current source inserted pointing to a, where Vth=Vab, all I would have to do would be multiply Vth*Is to find the power delivered by the source. But it tells me this is wrong by at least an order of magnitude. Help?
