hi,
i'm doing some calculation for the half wave recitifier circuit that built with a 1N4007 diode, a filter cap 10uF/35V or 2200uF/35v , transformer rating is 15-0 1A, load resistance 100 ohm or 10k ohm.
after construct the circuit using 10uf/35v and a 10k ohm. then i calculate the ripple voltage using this formula
Vr = Vp / fCR
i get Vr = 4.72V
then, i calculate the Vo using Vo = Vp - 0.5Vr
i get ~21.24V.
then, i compare my calculation with the waveform on the scope and DMM, as what i get is using DMM i get Vo=22V and from scope Vr = 4.0V
---------------------------------------------------------------------------
Now, i would like to go for 10uf/35V as filter cap and 100 ohm as load.
after calculation it seems like i get Vr = 472V. Could it be so high??!!!
can anyone help me on this?
thank you.
