Find the average value of output current for a 1-phase HW diode rectifier with R load, having RMS output current = 100A.

(a) 200R A

(b) 100/R√2 A

(c) 200/R√2 A

(d) 200/Rπ A

I had been asked this question in a national level competition.

This is a very interesting question from 1P-Diode Rectifiers HW-1 topic in section Diode Rectifiers of Power Electronics

Right answer is (d) 200/Rπ A

The best explanation: I(rms) = Vm/2R

Therfore, Vm = 200R

I(avg) = Vm/πR = 200R/πR.
