Question:

Consider the Zener diode circuit shown in Figure P2.20. Assume $V_{Z}=12 \mathrm{~V}$ and $r_{z}=0$.

(a) Calculate the Zener diode current and the power dissipated in the Zener diode for $R_{L}=\infty$.

(b) What is the value of $R_{L}$ such that the current in the Zener diode is one-tenth of the current supplied by the $40 \mathrm{~V}$ source?

(c) Determine the power dissipated in the Zener diode for the conditions of part (b).
