Consider the voltage-regulator circuit shown in Figure 2. The ac ripple voltage is 1 V
peak to peak. The dc (average) load voltage is 5 V. What is the Q-point current in the
Zener diode? What is the maximum dynamic resistance allowed for the Zener diode if the
output ripple is to be less than 10 mV peak to peak?
