WebI think it is misleading to say that a MOSFET has resistance. Pick some point on one of the curves you show. Find the slope of that line (actually the tangent of the line) at that point. The slope is Δ I / Δ V, which is 1 / R and R is the effective resistance of the MOSFET at the chosen voltage/current point.
