//Variables
VZ = 10.0 //Zener voltage (in volts)
RS = 1.0 //Series Resistance (in kilo-ohm)
RL = 2.0 //Load Resistance (in kilo-ohm)
VSmin = 22.0 //Minimum source voltage (in volts)
VSmax = 40 //Maximum source voltage (in volts)
//Calculation
IL = VZ / RL //Load current (in milli-Ampere)
IZmax = (VSmax - VZ) / RS - IL //Maximum value of zener current (in milli-Ampere)
IZmin = (VSmin - VZ) / RS - IL //Minimum value of zener current (in milli-Ampere)
//Result
printf("\n Maximum value of zener current is %0.3f mA.\nMinimum value of zener current is %0.3f mA.",IZmax,IZmin)
