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 causes the ripple voltage on the output of a capacitor-input filter?
Ripple voltage in a capacitor-input filter primarily arises from the charging and discharging cycles of the capacitor. When the rectifier conducts, the capacitor charges to the peak voltage of the input signal. As the load draws current, the capacitor discharges, causing the voltage to drop until the rectifier conducts again, resulting in a voltage ripple. The magnitude of this ripple depends on factors such as the load current, capacitance value, and input frequency.
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
How capacitor helps to improve the ripple factor?
A capacitor helps improve the ripple factor in power supply circuits by smoothing out the fluctuations in voltage that occur after rectification. When connected in parallel with the load, the capacitor charges during the peaks of the rectified voltage and discharges during the troughs, effectively reducing the voltage ripple. This results in a more stable DC output, which is particularly important for sensitive electronic devices. By minimizing the ripple, the capacitor enhances the overall performance and reliability of the power supply.
What happens to the output voltage of a rectifier if the capacitor becomes very leaky?
A leaky capacitor will act like a load therefore decreasing the DC and increasing ripple eventually the capacitor it will self destruct because of heating probaly taking out the rectifiers as well.
How can a capacitor reduce the effects of ripple voltage?
The smoothing capacitor converts the full-wave rippled output of the rectifier (which is left over AC signal) into a smooth DC output voltage A smoothing capacitor after either a half-wave or full-wave rectifier will be charged up to the peak of the rectified a.c. Between peaks of the a.c. the stored voltage will drop by a degree dependent on how much current is drawn from it by the load. The larger the value of the capacitor, the less drop there will be, and therefore less ripple when loaded.
How can capacitor smooth or reduce the ripple of the voltage produced by the rectifier?
when rectifier is on, the capacitor is almost transparent (it charges to the voltage provided from the rectifier) when rectifier is off, capacitor holds the peak voltage since it stored a charge during rectifier on time.
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 the ripple factor of a half wave rectifier?

What is the value of ripple factor in Half Wave Rectifier?

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 will happen if the capacitor is removed from the DC charger?
It will increase the ripple factor that the capacitor is in the circuit to smooth out.
How do you determine the size of acapacitor in a rectifier circuit?
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.
Significance of the ripple voltage on a rectifier circuit?
A: It really depends on the load requirement . Example driving a relay hi ripple with no capacitor is an advantage in efficiency for a sensitive amplifier it will cause mayhem with the performance
What will be the effect on ripple factor if the value of capacitor is reduced?
Ripples will increase if capacitance is decreased.
