Hi, I have the following circuit: http://i137.photobucket.com/albums/q208/infinitbelt/ProblemSet3Circuit1.png Also, the following is known: X=60 V R1= 10 Ω R2= 20 Ω R3= 10 Ω R4=5 Ω R5=20 Ω R6 = 5 Ω How do I go about finding a V-I characteristic of this circuit? I know that the slope of the graph is the resistance but I am confused as to how to start this one. I found the resistance across the source by using circuit reduction. I got that to be 32 ohms. So is the V-I characteristic just V = 32i? or is it just a constant line y = 60? (in this case V is on the y-axis and I is on the x-axis) Thanks!
