Repeat the exercise in Figure F-2, but use Vin – Vss = 9V. The answer is V
= 7.4 V
Repeat the exercise in Figure F-3, but use a 1 kΩ resistor. Answer: I = 3.4
mA.
Use V
I = 7.4 mA.
Repeat the exercise shown in Figure F-4 with one of the resistors at 470 Ω and
the other at 1 kΩ. Answer: I = 7.23 mA + 3.4 mA = 10.63 mA.
