[QUOTE="orangeincup, post: 4997907, member: 518656"] [h2]Homework Statement [/h2] The variable resistor R in the ciruit is adjusted for maximum power to Ro. what percentage of total power developed in circuit is transferred to R. [h2]Homework Equations[/h2] i=V/R [h2]The Attempt at a Solution[/h2] So my goal is to put a "fake" charge across v/2(the dependent source) of 1A facing upwards. The R0 is at the very top of the circuit(the one with no value, above 7.) Since I know i3=-1A I need equations for i1 and i2 5i1-2i2=217 -2i1+10i2=0 Solving for i1/i2.. i2=9.3A i1=47.1A From here, I know I need Vab which is V across the 1 ohm resistor minus V across the 3 ohm resistor 1(i2-i3)+3(i1-i3)=vab 1*10.3+3*47.1=vab 151.69=vab 151.69V/1A=151.69 ohms The answer is meant to be 3, I also solved it the other way(calculating for Voc and Isc) and got 3 ohms for my answer. I don't know what I did wrong using this method. [/QUOTE]
