a. Referring to Fig. 1.33, determine the transition capacitance at reverse-bias potentials of –25 V and –10 V. What is the ratio of the change in capacitance to the change in voltage?

b. Repeat part (a) for reverse-bias potentials of –10 V and –1 V. Determine the ratio of the change in capacitance to the change in voltage.

c. How do the ratios determined in parts (a) and (b) compare? What does this tell you about which range may have more areas of practical application?
