Hi guys,
I am stumped. I have tried inside out to solve the attached problem but I can not figure it out. It's driving me a little bit nuts as it looks like it couldn't be that hard... famous last words. I have attached several pics: The problem I can not solve is "Figure 6".
I have been able to logically solve Fig1 thru Fig5. I have also put a few pics of my workings to the previous resistor networks in case my approach is incorrect but only now it is showing, and someone else can see it..
The question is to calculate the resistance between points A and B, RAB.
There's no mention of voltage at any stage, its just all about the resistance.
I have included the answer to Fig 6 (80.5ohm). I have cross checked this with a simulation of the circuit, and that is the correct answer But how!!????
I have ended up trying by changing the points of A and B to try and understand the circuit better, and to try and figure out why I cant solve this last one, what it is that's different about it that I do not understand.. but unfortunately I am still not able to figure out the correct way to solve it. I've attached one of those attempts too.
I hope someone out there is up for shedding some light on this. I would really appreciate the help !
Thanks !!
