Hint: in my calculations below, to make math easier, i assume that the
diode = ideal(there is no 0.7 voltage drop across the diode)
Vrms = 0.707Vp => Vp = 14.1v, therefore Vp(load) = 14.1v assuming diode = ideal and Vdc = Vp/π = 14.1/π = 4.49v, which is pretty close to my screenshot(it says Vdc = 4.22 V ).
I want to compute Vdc. There is a formula for half wave sine: form factor = Vrms/Vdc = 1.57 . My naive mind says: Vdc = Vrms/1.57 = 10/1.57 = 6.369 . The simulator says Vdc = 4.22. :-(
I would like to use the form factor formula and get a correct result. What is my mistake?
