Figure shows the circuit symbol for a class of twoterminal devices called diodes. The i-v relationship for a specific pn junction diode is i = 5 × 10-17 e40 v - 1 A.
(a) Use this equation to find i and p for v = 0, ±0:1, ±0:2, ±0:4, ±0:8, and ±1:0 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 V. Do you think the model applies to voltages in this range? (d) Repeat (c) for v = -5 V.
