a. Based on a review of the characteristics of Fig. 5.126, which parameter changed the most with increase in temperature?

b. Which changed the least?

c. What are the maximum and minimum values of h_fe? Is the change in magnitude significant? Was it expected?

d. How does r_e vary with increase in temperature? Simply calculate its level at three or four points and compare their magnitudes.

e. In which temperature range do the parameters change the least?
