Question: a. Using the characteristics of Fig. 3.14a, determine ac at IB = 80 it A and VCE = 5 V. b. Repeat part (a) at

a. Using the characteristics of Fig. 3.14a, determine βac at IB = 80 it μA and VCE = 5 V.
b. Repeat part (a) at IB = 5 μA and VCE = 15 V.
c. Repeat part (a) at IB = 30 μA and VCE = 10 V.
d. Reviewing the results of parts (a) through (c), does the value of βac change from point to point on the characteristics? Where are the high values located? Can you develop any general conclusions about the value of βac on a set of collector characteristics?
e. The chosen points in this exercise are the same as those employed in Problem 23. If Problem 23 was performed, compare the levels of βdc and βac for each point and comment on the trend in magnitude for each quantity.
