Capacitor as a ripple filter in the rectifier circuit - difference in charging and discharging time
Most of the times attached picture is used to depict the use of Capacitor as filter in the rectifier circuit. I guess, i understand the broad concept but I am struggling with the fact that charging ...

What do I and V mean in C = It/V?
I am trying to determine what value capacitor I need to put after the full wave rectifier to get a smooth voltage for charging my battery. However, I don't understand which current and voltage do the ...

Vdc in ripple factor
V_p(rect) is the rectified unfiltered peak voltage
V_r(pp) is the peak-to-peak voltage after filtering by a capacitor
Here is a picture:
V_r(pp) is given by the expression:
Which I have no problem ...

Rectifier ripple voltage formula
So I thought the ripple voltage was approximated by the formula
Vr,pp = Vp / fRC
for a half-wave rectifier, and Vp/2fRC for a full-wave.
Yet simulation shows ...

What is a capacitor ripple current?
Suppose I have a simple full wave bridge rectifier, with resistive load. Is capacitor ripple current a charging or discharging current? Or maybe it is an avarage/RMS of any current flowing through a ...
