  1. 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

    2. 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°
