Figure 3.13. A graph is shown with the origin in the middle and all four quadrants showing. The vertical axis is labeled current and the horizontal one voltage. A heavy red curve passes through the origin and it goes to the right merged with the horizontal axis for about one quarter of an inch. Then it curves upward still moving to the right. As it rises from the horizontal axis the curvature increases until it ends at 2 and a half inches it is almost vertical. It ends at this point. Now back to the origin. The curve goes to the left merged with the horizontal axis until at 2 and 3 quarter inches it suddenly turns straight downward. It goes down for 2 and a half inches without moving any further to the left. There are no numbers on the graph. End verbal description.
