1. The problem statement, all variables and given/known data The problem and its solution are attached in the TheProblemAndSolution.jpeg file. 2. Relevant equations V = RI G = 1/R 3. The attempt at a solution I tried to understand what the solution said, but I'm still very lost. Here's what I'm stuck on.: When the solution says "Since each value of voltage gives only a single resistance value, the resistor is voltage controlled.", I don't see how it is the case that each value of voltages gives only a single resistance value. Similarly, the solution also says "[The resistor] is not current controlled since certain values of current give more than one value of resistance.", and I also don't see how it is the case that . I also don't see how the solution goes from Fig. 3 to Fig. 4; in an attempt to reverse-engineer the solution, I see that 5V / 2Ω = 2.5 A, which gives the vertical intercept, and I also see that the horizontal intercept is the value of the voltage source, which is 5 V, but I'm not sure whether or not those are coincidences. Also, am I missing something, or is the solution expecting me to get the (precise) values of 2.2 A, 1.9 A and 0.3 A, by just looking at Fig. 5 (which is Fig. 1 and Fig. 4 overlapped)? Any help in figuring out how to do this problem would be GREATLY appreciated!
