In the circuit shown in Figure 2–52 (p. 97), the Zener diode has a reverse breakdown voltage of 12V. RS = 50 Ohms, VS = 20V, and RL can vary from 100 Ohms to 200 Ohms. Assuming that the Zener diode remains in breakdown, find: (a) the minimum and maximum current in the Zener diode; (b) the minimum and maximum power dissipated in the diode; and (c) the minimum rated power dissipation that RS should have.

In the circuit shown in Figure 2–52 (p. 97), the Zener diode has a reverse breakdown voltage of 12V. RS = 50 Ohms, VS = 20V, and RL can vary from 100 Ohms to 200 Ohms. Assuming that the Zener diode remains in breakdown, find:

(a) the minimum and maximum current in the Zener diode;

(b) the minimum and maximum power dissipated in the diode; and

(c) the minimum rated power dissipation that RS should have.
