## Homework Statement

Using the smooth curve for V vs. I and find values for R for the seven values of V and I.

## Homework Equations

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.
