Document Summary
Thevenin and norton theorem: circuits can, at times get complex. While loop, mesh and node analysis is possible. If we break these complex circuits into separate networks, they might be a bit easier to handle. Ex: compute current through and voltage drop across rl. Monday, september 10, 2018: to nd voc, we need to nd the voltage across r1. R5 does not come into play when we"re looking for voc because there is no current ow through. We apply kvl to the rst mesh and solve for. I1 then multiply it by the value of r1: vth = voc = vr1. * 4 = 9. 33v: next, we have to nd the thevenin resistance. To do this, we short out any voltage sources and open any current sources and then compute the equivalent resistance. In this case r3 & r1 are in parallel then it"s result is in is in series with r5 a)
