What is the difference between with capacitor rectifier and without capacitor rectifier?
To know the difference between capacitor and non capacitor rectifiers one must study what is the function of filter part.the filter part consists of capacitors or inductors or combination of both. the output of a simple diode rectifier is pulsating dc which means it consists of both dc part and ac part. filters are used to remove the ac part from such an output. capacitor filter means that a capacitor is used for filtering out the ac part. non capacitor or inductor filter means that an inductor is used for filtering out the ac part. There is another type called pii filter where both inductor and capacitor are used. Pii filter is the best kind of filter available
What is advantage of capacitor filter over RC filter?
sounds same to me.maybe you meant advantage of LC filter over RC filter
Can you control voltage fluctuations by using capacitor?
By using C-filter
Effect of the capacitor to the low frequency waveform?
The differential equation for a capacitor is dv/dt = i/c. Set that up in a circuit and force an AC power source, such as sin(theta), and you will see that lowering the frequency will increase the equivalent resistance. I'll leave that exercise for you. The net result is that a series capacitor is a high-pass filter, while a parallel capacitor is a low-pass filter.
What do you mean the 1st order and 2nd order filter circuit?
1st order that has in low pass filter one resistor and a capacitor in parellal to ground .And the 2nd order filter has one pole as a above and second as resistor in series and capacitor for gain and the refers to the number of components (C,L).
What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
What is the advantage of capacitor filter over inductor filter?
An inductive filter is in fact an LC circuit in which an inductor is connected in series with the capacitor. This arrangement is also known as a low-pass filter. http://www.answers.com/topic/inductive-filter
Output voltage of half wave rectifier without capacitor filter is less or more than rectifier with capacitor filter?
less
What are the advantages and disadvantages of pi section filter over a shunt capacitor filter?
1.More output voltage compared to shunt capacitor filter. 2.Less No of ripples. 1.Higher cost relative to shunt capacitor filter. 2.Larger in size.

What is the effect of the filter capacitor on the output wave shape of the rectifier?
The larger the cap the smaller the ripple at the power supplies output. It smooths the rectifiers output waveform.
What is a filter capacitor?
Capacitor has many applications in electronics circuits, one of its application is in FILTERS. Mainly two types of Filters are formed with the help of capacitor namely, i)Low Pass Filter(LPF) ii)High Pass Filter(HPF) Impedance of capacitor is inversely propotional to the frequency, therefore a capacitor in series with resistor will act as Low Pass Filter. since all the high frequency are passed to ground.
What is the difference between an inductive low pass filter and a capacitive low pass filter?
Where you are measuring. A simple filter will be two elements - a capacitor or inductor and a resistor. A capacitor will tend to "trap" low frequencies. In the case of a lowpass filter made of a capacitor and resistor, the output voltage will be measured across the capacitor. Inductors are the opposite, so the output would be across the resistor.
Can a radial capacitor react different than an axial capacitor when being used as a filter for EMF?
Yes. The inductance of a radial capacitor can be different than an axial capacitor, particularly at RF, so the reaction as a filter for EMF could well be different.
How does a capacitor acts as a filter?
The cutoff frequency of filter depends upon the value of capacitor and resistance. Therefore, below cutoff frequency or above this frequency, capacitor allow to pass all other frequencies.
