a. Sketch the maximum-power curve of P_D = 200 mW on the graph of Fig. 17.56. List any noteworthy conclusions.
b. Determine βdc (defined by I_C/I_F) for the system at V_CE = 15 V, I_F = 10 mA.
c. Compare the results of part (b) with those obtained from Fig. 17.55 at I_F = 10 mA. Do they compare? Should they? Why?
