What is the difference between a polarized capacitor and a non-polarized capacitor?

Answer 1

For analog application that need swinging signal from positive to negative that will not work for you. But for DC applications where signal is always positive (or negative) that will be ok to exchange the capacitors with no harm to your circuit.

Hope that will help you,

if you need to find good quality electronic components i advise you to check www tmartis com, you can find a lot of good stuff there.

Answer 2

A polarized capacitor uses a special form of dielectric that only allows charge in one direction. A non-polarized capacitor does not have that restriction.

The advantage of a polarized capacitor is that, since the dielectric is much thinner, it can be fabricated with very large capacitance in a very small space. In fact, some capacitors have greater than one farad capacity in less than one cm3.

The disadvantage of a polarized capacitor is that you can only charge it in one direction, but this is not an issue in most uses, because these larger capacitors are most often used in power supplies.

Answer 3

In unpolarized light , vibrations takes place randomly oriented directions perpendicular to the travel of wave .Whereas , in polarized light vibration takes place parallel to the travel of wave.

Answer 4

In all likelihood, yes. But it will most likely be more expensive to do so - you need to match the same size, and voltage rating.

Answer 5

If you use a polarized capacitor in an application that requires a non polarized capacitor, you will destroy the capacitor.
