For a single phase half-wave thyristor circuit with R load, the input power factor is given by

(a) rms source voltage/total rms line current

(b) rms input power/power delivered to the load

(c) cos α

(d) power delivered to load/input VA

This question was posed to me in an international level competition.

My enquiry is from Single-Phase HW AC-DC-2 in section Converters of Power Electronics
