Using the smooth curve for V vs. I and find values for R for the seven values of V and I.
P = VI
R ≠ V/I
The Attempt at a Solution
I got the slope of the tangent line and got .002Ω for each point... Doesn't seem like a correct value. Can someone tell me how to get R. It is hinted something about the tangent line. I can't use the formula R = V/I for some reason stated on the paper.
