A zener diode voltage regulator is shown in Figure 4. The zener diode is characterized by Vz = 5.1 V and Rz = 10 12. Sketch the current-voltage characteristic of the diode. Indicate the threshold voltages and the slope on your graph. Identify the regions where the diode is off, forward and reverse conducting. Plot the output voltage V. as a function of IL. With Vs = 9 V and Rs = 1 k12, over what range of values of the load resistor RL will the regulator maintain a regulated voltage of approximately 5.1 V across this load?
