A single phase half wave rectifier is feeding a resistive load. Input voltage v = Vm sin ωt. The output dc voltage is Vdc and output rms voltage is Vrms . If firing angle is 180°, Vdc and Vrms respectively are

[A]. 0 and 0
[B].
[C]. 0 and - Vm
[D].

Answer: Option A

Explanation:

Put a = 180° in Eqs

Otherwise also a = 180° means no conduction.

Hence zero output voltage.
