The variable resistor R in the ciruit is adjusted for maximum power to Ro. what percentage of total power developed in circuit is transfered to R.
The Attempt at a Solution
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
Solving for i1/i2..
From here, I know I need Vab which is V across the 1 ohm resistor minus V across the 3 ohm resistor
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.
