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.
Regarding Capacitors- can any general capacitor work on a circuit diagram that shows a polarized capacitor or do you need a special capacitor for polarization?
A Polarized capacitor means that the capacitor is polarity sensitive. if you were to connect the capacitor incorrectly the capacitor would blow up. A capacitor that is marked as being polarity sensitive will have the negative lead labeled usually with a white strip. These capacitors can only be used in conjunction with a dc source. Always consult a professional when installing electrical equipment.
What happen to the energy stored in the capacitor while the capacitor is discharging?
It flows out of the capacitor into the external circuit
How one can know that what kind of capacitor to use in circuit?
paper capacitor
Can I check the capacitor value by using analog or multimeter?
You can see if the capacitor charges and discharges with an ohmmeter. You can check the value of the capacitor if the multimeter has the facility. With an ESR meter you can establish the value of the capacitor while in circuit.
How do unpolarized waves look like?
Unpolarized waves will look random.
What does electrolytic capacitor do?
The same thing as any other capacitor does (i.e. oppose changes in the voltage across it) except:it has much greater capacitance per volume than other capacitorshas higher leakage current than other capacitorsis polarized when all other capacitors are unpolarized
What is unpolarized?
Unpolarized energy is when there are vibrations which are produced randomly in spatial orientation. This will happen in more than one plane.

What is a non polarized capacitor?
A polarized capacitor is one which has a polarity, positive on one terminal, negative on the other. This makes it superficially look like a battery. In use, the capacitor has its positive voltage always higher than that on the negative terminal, it matters that this is the case and this gives rise to the term polarized. This sort of capacitor is commonly found in power supply filters.
Why are sound wave unpolarized?
Sound waves - at least in liquids and gases - can only be longitudinal.
Differentiate polarized and unpolarized light. Describe two ways by which light can be polarized.?
scattering and by reflection
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
What two facctors determine the capacitive reactance of a capacitor?
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor
Can you by-pass a capacitor in an electric motor?
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
Polarization is the process of transforming unpolarized waves to polarized waves What methods are valid ways to polarize waves?
transmission and scattering
Why gang capacitor called so?
GANG capacitor is called so because it group of capacitor
