I have a I vs. V graph (I on x-axis, V on y-axis) and I need to figure out how to find the resistance from this.(adsbygoogle = window.adsbygoogle || []).push({});

I know that R = V/I when the graph is linear, but I have a curved graph...

I was thinking maybe to sketch a tangent line across each point that I need to figure out its resistance and find the resistance by using ΔV/ΔI.

Would that be correct?
