although the AC signal is rectified the output which we get is the pulsating DC which is not desired because many appliances wok on plain DC voltage . The pulsating DC can be viewed as AC + DC component of the signal
ripple factor of a rectified circuit is the ratio of AC component of signal to the DC component of the same rectified output signal. higher the ripple factor says that the signal is not smooth so lesser is its application.
the components used to smooth these type of signals or to remove the 'ripple voltage' as called filters
A: Without a capacitor to smooth out the DC there will be no ripple just pulsating DC at double of the input frequency. But if you add a capacitor then the ripple will be directly related to the load.
Rippling can be reduced by incorporating an inductor or capacitor filter. The most common type of filter out there is a capacitive filter.
The ripple factor of Half wave rectifier is the ratio of the rms value of the ac components to the dc value of the component

What is advantage of precision full wave rectifier over precision half wave rectifier?
Either less ripple voltage with the same filter capacitance, or similar ripple voltage with smaller filter capacitances (and thus physically smaller filter capacitors).
What is the relationship of the input frequency and output frequency in a FULL-wave rectifier?
The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave or triangle wave. If the input is a square wave, the output is DC. If the input is a sawtooth wave, the output is a triangle wave of the same frequency.
What are the advantage and disadvantage of full wave rectifier with filtre?
either less ripple or ability to use smaller filter
If the input frequency to a full wave rectifier is 400Hz what is the ripple frequency?
twice the frequency that is rectified.
Where do you use a full wave rectifier?
Right: Example out of a transformer AC to DCAnother Answer:Anywhere there is AC and DC is required. A full wave rectifier is a circuit that produces a DC pulse using both halves of an AC sine wave - full wave rectifier.
What is ripple factor of the Full-wave rectifier?
The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482
What is the importance of ripple factor?
Ripple factor ripple factor is very important in deciding the efficiency of the rectifier .ripple factor give the total power converted AC input to the DC output. Ideal ripple factor should be zero and power factor 1. Ripple factor of half wave rectifier 1.21 and full wave rectifier is 0.48.
What is the value of ripple factor in Half Wave Rectifier?
1.21
What is the value of the ripple factor of a half wave rectifier?
1.21
How you determine ripple factor of a half wave rectifier?
when a.c convert in d.c then some components of a.c remain with it called ripple factor
What is the frequency of ripple components in the output of capacitor filter?
It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
What is the lowest ripple frequency of half wave rectifier?
The ripple frequency of a half-wave rectifier is the same as the input frequency.
What is ripple frequency of 50 Hz 3 phase full ac supply?
A single phase half wave rectifier outputs ripple the same frequency as the input. A single phase full wave rectifier outputs ripple fundamental twice the input frequency (assuming balanced recitfiers). A three phase full wave rectifier outputs ripple fundamental six times the input frequency. So 50 Hz input would yield 300 Hz ripple. See Sources and Related Links for more information.
