a. Using the characteristics of Fig. 3.24, determine β_ac at I_C = 14 mA and V_CE = 3 V.

b. Determine β_dc at I_C = 1 mA and V_CE = 8 V.

c. Determine β_ac at I_C = 14 mA and V_CE = 3 V.

d. Determine β_dc at I_C = 1 mA and V_CE = 8 V.

e. How does the level of β_ac and β_dc compare in each region?

f. Is the approximation β_dc ≅ β_ac a valid one for this set of characteristics?
