For HWR ckt. avg value=Vm/π and RMS value=Vm/2.
For FWR ckt avg value=2Vm/π and RMS value=Vm/√2.
For FWR ckt avg value=2Vm/π and RMS value=Vm/√2.

For HWR;
Vrms = 1.57Vavg.
Vrms = 1.57Vavg.

Answer b is correct Vrms= Vm/π=20/π,
Vavg=VM/2=20/2=10.
Vavg=VM/2=20/2=10.

For dc, half wave rectifier.
Vavg=Vm/π and Vrms=Vm/2.
and;
For dc, full wave rectifier.
Vavg=2Vm/π & Vrms=Vm/π2.
Vavg=Vm/π and Vrms=Vm/2.
and;
For dc, full wave rectifier.
Vavg=2Vm/π & Vrms=Vm/π2.
