//Variables
VS = 30.0 //Source voltage (in volts)
RS = 240.0 //Series resistance (in ohm)
Vz = 12.0 //Zener voltage (in volts)
RL = 500.0 //Load resistance (in ohm)
//Calculation
VL = Vz //Voltage drop across load (in volts)
IS = (VS - Vz) / RS //Current through RS (in Ampere)
VRS = IS * RS //Voltage drop across series resistance (in volts)
IL = VL / RL //Load current (in Ampere)
IZ = IS - IL //Zener current (in Ampere)
//Result
printf("\n Load voltage is %0.3f V.\nVoltage drop across series resistance is %0.3f V.\nCurrent through Zener diode is %0.3f A.",VL,VRS,IZ)
