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.

Unit of ripple factor?
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.
What is ripple voltage in 12 volt power supply?
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
Methods of calculating Ripple voltage in supply without using oscilloscope?
Measure AC voltage with multimeter. It is easiest way to check how big ripple is. There is no way to 'calculate' value.
What is ripple factor?
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 ...
What happens to ripple frequency when one diode is removed from bridge?
actually a diode is forward biased by at least 0,7 volts.so what it means is that when it is removed that 0,7 voltage drop on the diode is eliminated thus increasing ripple voltage

What cause excessive ripple voltage from a power supply.?
I think the cause of ripple voltage would be from a bad ground or capacitve voltage.

How is ripple measured?
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.
What is diode ripple?
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.
What is the formula for ripple voltage in current?
V(ripple)= V(rms) / V (DC)

What is the effect of load resistance on ripple voltage in presence of filter capacitor?
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.
How do you check ripple voltage in an alternator?
Connect an oscilloscope and check the screen for a smooth constant ripple pattern at high revolution and low revolution.
How do you measure amplitude of a ripple?
Most true RMS voltmeters can measure the value of a ripple voltage on top of a DC supply, when you place it in AC mode. You can also place a small capacitor in series with a DC voltmeter and that would measure the ripple. The real way to do this, because ripple voltage is not sinusoidal, is to use an oscilloscope, particularly if you want the peak values.
If we were midgets at a football game and we did the wave wouldn't that be called a ripple?
yes, it would be called a ripple.....
