a. Using the characteristics of Fig. 3.7 and 3.8, determine I C if V_CB = 5 V and V B_E = 0.7 V.
b. Determine V BE if I_C  = 5 mA and V C_B = 15 V.
c. Repeat part (b) using the characteristics of Fig. 3.10b.
d. Repeat part (b) using the characteristics of Fig. 3.10c.
e. Compare the solutions for V BE for parts (b) through (d). 

Can the difference be ignored if voltage levels greater than a few volts are typically encountered?
