A two winding transformer is feeding a single phase half wave rectifier circuit. The load is purely resistive. The rms value of transformer secondary current is Is and rms value of load current in Irms. Then

[A]. Is = Irms irrespective of the value of firing angle
[B]. Is = 0.5 Irms irrespective of the value of firing angle
[C]. Is = Irms if firing angle is less than 30°
[D]. Is = Irms if firing angle is more than 30°

Answer: Option A
