A non-ohmic circuit element has the current-versus-potential difference (
(I\) vs. \(V\)) characteristic curve shown in the graph. At operating point \(P\), the potential difference across the element is \(V_0 = 4.0\text{ V}\) and the current through it is \(I_0 = 2.0\text{ mA}\). The dashed line is tangent to the curve at point \(P\) and intersects the horizontal axis at \(V = 2.0\text{ V}\). Which of the following statements correctly relates the features of the graph to the resistance properties of the element at point \(P\)?
