+//Given Data

+//From Figure 3.28

+

+V=15;//value of voltage source in volts

+Vz=10;//zener breakdown voltage in volts

+Rs=300;//series resistance R in ohms

+Rp=900;//shunt resistance R' in ohms

+Izmax=10;//maximum zener current in milli-amperes

+

+//Solution

+

+//Assuming ideal diode Vz=12V and Rz=0 ohms

+Vrs=V-Vz;//voltage across resistor in volts

+Irs=Vrs/Rs*1000;//current through resistor R in milli-amperes

+Irp=Vz/Rp*1000;//current through resistor R' in milli-amperes

+

+Iz=Irs-Irp;//current through diode in milli-amperes

+

+if Iz<Izmax then

+    printf("The diode is properly biased.\n");

+else printf("The diode is not biased properly.\n");

+end

+

+Pd=Vz*Iz;//power dissipation in milli-watts

+

+printf("The dissipated power = Pd = %.1f mW",Pd);
