1. The problem statement, all variables and given/known data You are working with a device in a black box which has two terminals, which are in turn, part of a larger circuit. You measure the voltage and the current at the terminals and record the following: vi (V) | i1 (A) 100 | 0 120 | 4 140 | 8 160 | 12 180 | 16 a: construct a circuit model for this device using a current source and a resistor b: How much power will the device deliver to a 20 ohm resistor? 2. Relevant equations ???? Ohms Law? 3. The attempt at a solution I haven't ever seen anything like this before in my class, my textbook offers no help that I can think of to even begin with this. All I know is that at V=100, A = 0, Resistance would be unavailable due to division by 0. V=120, A = 4, R=30 V=140, A=8, R = 35/2 V=160, A=12, R = 40/3 V=180, A=16, R = 45/4 I am absolutely lost here guys.. I don't know if I have a hard teacher (Or a lousy teacher), or if I should take the humility route and wonder if I'm not meant to go for EEing because I cannot figure this out. But then again, this entire homework he has assigned us has been chalked full of material he hasn't covered that I had to research on my own.
