//Variables
VS = 15.0 //Input voltage (in volts)
VZ = 8.3 //Zener voltage (in volts)
beta = 100.0 //Common-emitter current gain
R = 1.8 //Resistance (in kilo-ohm)
RL = 2.0 //Resistance (in kilo-ohm)
VBE = 0.7 //Voltage across base-emitter junction (in volts)
//Calculation
VL = VZ - VBE //Voltage across load (in volts)
VCE = VS - VL //Collector to emitter voltage (in volts)
IR = (VS - VZ)/ R //Current through R (in milli-Ampere)
IL = VL / RL //Load current (in milli-Ampere)
IB = IL / beta //Base current (in milli-Ampere)
IZ = IR - IB //Current through Zener (in milli-Ampere)
//Result
