a. Using the characteristics of Fig. 3.13a, determine b dc at I_B = 60 mA and V_CE = 4 V.

Fig. 3.13a

b. Repeat part (a) at I_B = 30 μ A and V_CE = 7 V.

c. Repeat part (a) at I_B = 10μ A and V_CE =10 V.

d. Reviewing the results of parts (a) through (c), does the value of b dc change from point to point on the characteristics? Where were the higher values found? Can you develop any general conclusions about the value of b dc on a set of characteristics such as those provided in Fig. 3.13a?
