V(ripple)= V(rms) / V (DC)
For Half wave rectification: Vr(HW) = I/(C*F) HW= Ripple Voltage I = Direct Current C= Capacitance F= Frequency of the ac line. For full wave rectification: Vr(HW) = I/(2*C*F)
In a switching DC-DC voltage converter, the oscillatory nature of the switching circuit generates a small "ripple" effect in the output voltage which is supposed to be minimized via careful design of the overall circuit. The output current of this type of converter typically flows through a diode into the rest of the system. The voltage measured at the cathode of this diode will exhibit the aforementioned ripple.
Power is voltage times current.
Ripples in electricity are usually defined as small, unwanted variations due to direct current. The effect of using a filter capacitor in this environment may vary, but usually has a smoothing effect on the ripple.
You reduce ripple voltage by adding a low-pass filter. In the simplest case, you put a capacitor after the rectifier. The peak voltage will be the rectifier output voltage less the forward bias of the rectifier, while the minimum voltage will depend on current and capacitance. In a more complex case, you could use an LC filter, making the peak voltage smaller. Specifics are dependent on the power and performance requirements.

Ripple, in DC power supplies, is technically unitless. Ripple voltage is specified in Volts/Volt, or a percentage. For example, a 12VDC power supply with 120mV (pk-pk) of ripple voltage is (0.12/12) = 1% ripple voltage.
Ripple voltage, in the presence of a filter capacitor, is inversely proportional to load resistance. If the load were zero (resistance infinite), then there would be no ripple voltage. As the load increases (resistance decreases), the ripple voltage increases. The ripple waveform will appear to be sawtooth, with the rising edge following the input AC from the diode's conductioin cycle, and with the falling edge either being linear or logarithmic, depending on load. If the load is resistive, without a regulator, the falling edge will be logarithmic. If the load is constant current, such as with a regulator, the falling edge will be linear.

I think the cause of ripple voltage would be from a bad ground or capacitve voltage.
Ripple factor (γ) may be defined as the ratio of the root mean square (rms) valueof the ripple voltage to the absolute value of the dc component of the output ...

Ripple voltage is a voltage with an impure wave that isn't stable at all. Usually when you overload an AC to DC converter, it tends to do that.
A: Ripple is a residual voltage evident as voltage following the AC input frequency. The ripple magnitude is a function of not enough of both filtering capacitance or overloading the output. Increasing capacitance will reduce the ripple or reducing the loading
Usually with an oscilloscope which shows a graph of the voltage, and then the peak-to-peak ripple voltage can be read off the screen.
