Avg.value = 0.636*Max.value.
Max.value = 12/0.636 = 18.86.
but,
RMS value = Max.value/1.414.
RMS value = 18.86/1.414=13.34.
So, the option is [A].
Max.value = 12/0.636 = 18.86.
but,
RMS value = Max.value/1.414.
RMS value = 18.86/1.414=13.34.
So, the option is [A].

Why we are not directly taken formula for half wave rectifier.
Form factor= (rms/avg).
Form factor= (rms/avg).

RMS value = V(peak value)*.707
V(average value)= Vpk*.637
Therefore, RMS valu =Vav*(.707/.637)
Vrms = 12*1.11 = 13.31= 13.33.
V(average value)= Vpk*.637
Therefore, RMS valu =Vav*(.707/.637)
Vrms = 12*1.11 = 13.31= 13.33.

Imax=Irms/1.414
Imax=1.57*Iav
Imax=1.57*12=18.84
Irms=18.84/1.414
Irms=13.33V
Imax=1.57*Iav
Imax=1.57*12=18.84
Irms=18.84/1.414
Irms=13.33V
