∙ 9y agoRipple factor can be defined as "the ratio of the root mean square (rms) value of the ripple voltage to the absolute value of the dc component of the output voltage." This is usually expressed as a percentage.

it can be measured by
RF = vrms / vdc

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 the ripple factor of full wave rectifier?
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
What is ripple factor of sinusoidal have peak ripple of 2v on an average of 50v?
Vp=2 Vdc=50 r=Vrms/Vdc Vrms=Vp/1.121 so r=0.028
How ripple factor is eliminated by capacitor in a rectifier?
ripple can understand as rise in sine wave.thus ripple-less means a straight line parallel to x-axis i.e. bump-less line.capacitor is a component which store charge.it charge through a.c. and behave as battery on full charge.and we all know battery gives a d.c. i.e. ripple less graph.
What is ripple frequency-?
How often the ripple occurs i.e. times the ripple occurs per second. The ripple should be a repeating pattern. Figure out where the ripple repeats and measure how long each repetition takes. Measure this in seconds. The frequency is 1/Time where time is the time measured previously.
In which case ripple factor is minimum?
when is ripple fator minimum
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.
Derive the expression for ripple factor of pi filter?
ripple factor:=21/2 /3 *Xc/XL
What is ripple factor of the Full-wave rectifier?
The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482
Why you need to calculate ripple factor in terms of form factor?
Ripple factor and form factor both are inerrelated to each other since they represent the extent to which filtering is done(ripple) and rms value of ac is greater than the average value(form). ripple factor=Vr(p-p)/V(dc) form factor=V(rms)/V(av)--Jivan Nepali
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 ideal value of ripple factor?
Zero

What will be the effect on ripple factor if the value of capacitor is reduced?
Ripples will increase if capacitance is decreased.
