[QUOTE="YellowBelliedMarmot, post: 5499290, member: 594265"] [h2]Homework Statement [/h2] [ATTACH=full]102088[/ATTACH] Find Vth and Zth. frequency = 2kHz [h2]Homework Equations[/h2] w = 2 * (pi) * f Z[SUB]L[/SUB] = j w L Z[SUB]C[/SUB] = -j / (w * C) V = I*Z Z[SUB]R[/SUB] = R [h2]The Attempt at a Solution[/h2] At first I tried using nodal analysis which I receive the value V = 0 v. I believe this is because this circuit only has dependent voltage sources. Therefore, the Vth is just 0 v. 10mH ---> j125.7 1uF ---> -j79.6 100 ohms ---> 100 w = 2*(pi)*2000 = 12566.37 Essentially, I am stuck. I have some theories as to what I can do though. I remember from DC circuit analysis that we can either add a 1v or a 1A (the number is arbitrary) source between terminals a and b, but I'm not sure what to do beyond that. Could I add a 1A (i.e. 1*cos(wt)) between the terminals, and then do nodal analysis? Then after that, would I take that voltage and divide it by the 1A (1cos(wt)) AC source to get the Zth? And as I mentioned above, wouldn't the thevenin equivalent of this circuit not even have a Vth since there's no independent sources? [/QUOTE]
