Figure P2-9. shows the circuit symbol for a class of two-terminal devices called diodes. The \(i-v\) relationship for a specific \(p n\) junction diode is \(i=5 \times 10^{-17}\left(e^{40 v}-1ight) \mathrm{A}\).

(a) Use this equation to find \(i\) and \(p\) for \(v=0, \pm 0.1, \pm 0.2\), \(\pm 0.4, \pm 0.8\), and \(\pm 1.0 \mathrm{~V}\). Use these data to plot the \(i-v\) characteristic of the element.
(b) Is the diode linear or nonlinear, bilateral or nonbilateral, and active or passive?
(c) Use the diode model to predict \(i\) and \(p\) for \(v=5 \mathrm{~V}\). Do you think the model applies to voltages in this range?
(d) Repeat (c) for \(v=-5 \mathrm{~V}\).
