Question:

Consider the Zener diode circuit in Figure 2.19 in the text. Assume parameter values of $V_{Z O}=5.6 \mathrm{~V}$ (diode voltage when $I_{Z} \cong 0$ ), $r_{z}=3 \Omega$, and $R_{i}=50 \Omega$. Determine $V_{L}, I_{Z}, I_{L}$, and the power dissipated in the diode for

(a) $V_{P S}=10 \mathrm{~V}, R_{L}=\infty$;

(b) $V_{P S}=10 \mathrm{~V}, R_{L}=200 \Omega$;

(c) $V_{P S}=12 \mathrm{~V}$, $R_{L}=\infty$; and

(d) $V_{P S}=12 \mathrm{~V}, R_{L}=200 \Omega$.
