This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask the answer of. Earn your diploma.
Basically, a capacitor stores input energy for later release. Some common uses of capacitors:
Filters are circuits consisting of resistors and capacitors (RC) or inductors and capacitors(LC) to filter unwanted signal components like noise,frequency,etc.
Filters can be classified into many types based on different categories.
Based on frequency filtering:
1. Low pass(to allow low frequency components)
2.High pass(to allow high frequency components)
3.Band stop or notch (to reject a particular band of frequencies)
4.Band pass(to allow the particular band of frequencies)
5.All pass(to allow all the frequencies)
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
a capacitor have a property it oppose any change of voltage
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
the capacitor and its associated resistor set the time constant.
control the flow of current..
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.

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

The emitter bypass capacitor, in a typical common emitter configuration, increases gain as a function of frequency, making a high pass filter. Removing the capacitor will remove the gain component due to frequency, and the amplifier will degrade to its DC characteristics.
less
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.
The function of a capacitor in a washing machine is to store a charge. This charge is what starts the washer.

A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the 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.
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.
