In other words, as polarized capacitor is bigger and maybe more expesnive, what conditions that I have to use polarized cap instead of non-polarized? Thanks so much for help!

Polarized capacitors are useful for single direction systems. The gate only opens one way and the lead is always singular in its transfer of power. Because of this the power is at full when it crosses the board and the Resistance is must be manipulated to make sure the power does not overload the system. As an example, most of the older laser systems worked off a polarized capacitor, when activated the capacitor discharged and all the power drained to a single pole. Thus the laser would fire in one burst until the entire capacitor was discharged.
Non-polarized or dual gated systems are omni directional and therefore omni systemic. Meaning the power flow can be multi directional, however because of the multi directional flow the power is decreased more quickly and dispersed over a wider area. Thus it cannot be as useful due to resistance across the board. However non-polarized capacitors work well within the atmosphere of amplifiers, and other more commercially accepted applications. However remember that all capacitors take time to recharge, and must be fully discharged before they can be recharged. Damage could occur when attempting to ram charge any kind of capacitor.

The polarization of a capacitor doesn't really have any pros/cons itself. However, the type of capacitor does make a difference, and usually the type of capacitor will determine if it is polarized.
There are multilayer ceramic, ceramic disc, multilayer polyester film, tubular ceramic, polystyrene, electrolytic, and many more. Each type of capacitor has different pro/cons, for example electrolytic are usually polarized and generally have bad leakage currents, but can be built for large capacitances.
Depending on what you want/need will determine the type of capacitor you need. I can't go over all the pros/cons of each type, you'll have to use google, or wikipedia for that.
As far a polarization is concerned the only con is that current can only flow one way into it, otherwise it will explode.

Capacitors are non polarized devices They become polarized when electrolyte is added to increase the capacity (capacitance) Polarized (DC) are used all over electronics stuff Non-polarized are used in power electronics as well as audio and very many electronics as well. Hope this properly answers your question Guru

Typically the polarized capacitors have more capacitance for a given physical size. The main use for them is in the filtering circuits of a power supply

Polarized capacitors are typically used in DC applications. A polarized cap could be used in AC application because there is no polarity.

The non-polarized capacitor doesn't have ice so you cannot make iced tea. Am I right? Huh?

COULD NOT AGREE MORE WITH YOU DMB!!!
Gate in a capacitor??? Yeah, right....
"However remember that all capacitors take time to recharge, and must be fully discharged before they can be recharged."
Fully discharged before they can recharge..... that one is really something.
Yahoo should use this answer as an example of not to trust everything you read in here....
