//Variables
Idc = 0.5 //dc current (in Ampere)
Vrms = 100.0 //Rms voltage (in volts)
alpha = 45.0 //Firing angle (in degree)
Idc = 0.5 //dc current (in Ampere)
//Calculation
alpharad = alpha * %pi / 180.0 //Firing angle (in radians)
Vm = 2**0.5 * Vrms //Peak voltage (in volts)
Vdc = Vm / (2 * %pi)*(1 + cos(alpharad)) //Average voltage (in volts)
RL = Vdc / Idc //Load resistance (in ohm)
//Result
printf("\n The value of resistance to limit the average current to 0.5 A is %0.2f ohm.",RL)
