80. Since values from the referred-to graph can only be crudely estimated, we do not present a graph here, but rather indicate a few values. Since R = V / i then we see R = when i = 0 (which the graph seems to show throughout the range –

Unformatted text preview: < V < 2 V) and V ≠ . For voltages values larger than 2 V, the resistance changes rapidly according to the ratio V / i . For instance, R ≈ 3.1/0.002 = 1550 Ω when V = 3.1 V, and R ≈ 3.8/0.006 = 633 Ω when V = 3.8 V....
