Question $1$

In the Zener$-$regulated power supply shown in Fig. $1,$ the input voltage $v_l$ has an RMS value of $15$ V $,$ and the operating frequency is $60$ Hz $.$ The circuit includes a resistor $R=100,$ and a capacitor $C=1000F.$ The diodes $D_1$ and $D_2$ each have an on$-$voltage of $0\mathrm{.}75$ V $,$ while the Zener diode D $3$ has a Zener voltage of $15$ V $.$ This power supply is designed to provide power and bias for an NMOS transistor and you are required to analyze it$.$
