Type your answer here... As per the definition of capacitor it is a device which made up of dielectric material in between two parallel metal plates. Even two metal plates placed parallel in open area will result in capacitance since air is also dielectric in nature..

What are types of capacitor?
Electrolytic capacitors are capacitors in which one or both of the plates is a non-metallic conductive surface, or in other words, an electrolyte. Electrolytic capacitors come in a variety of types including: aluminum electrolytic capacitor; tantalum; and a solid aluminum electrolytic capacitor with organic semiconductor electrolyte or OS-CON.
Why do you use a dc capacitor in table fans while an ac capacitor in a ceiling fan?
there is no separate capacitors for AC and DC. All capacitors are same. Electrolytic capacitors are manufactured by creating a die-electric by chemical etching or electroplating on one plate. Such capacitors when connected in AC circuit dislodges the die-electric material and thus results in short circuit between the two parallel plates of the capacitor. For AC circuits only non-electrolytic capacitors should be used. The common type is oil impregnated paper capacitor.
Does 001 farad of capacitor have polarity?
Only electrolytic capacitors (tantalum capacitors are a type of electrolytic capacitor) are polarized.0.001 farad = 1000 microfaradThis is a value that is too large for any practical capacitor except an electrolytic, so yes it will be polarized.
Can you explain why oil filled capacitors must be used for capacitor run motors instead of the more economical ac electrolytic types?
Electrolytic capacitors cannot be used on an AC (alternating current) system.
How ceramic capacitors can do filtering in replacement of electrolytic capacitors?
Electrolytic capacitors do a very good job of bulk filtering, but they have poor high frequency performance due to distributed inductance. The ceramic capacitor has excellent high frequence response, and will often be used in parallel to the electrolytic to filter out fast rise time step changes in current demand.
What are polar capacitors?
All electrolytic capacitors (e-caps) are polarized capacitors whose anode electrode (+) are made of a special metal on which an insulating oxide layer originates by anodization (forming), which acts as the dielectric of the electrolytic capacitor.
What is the difference between electrolytic capacitors and normal capacitors?
because normal capacitors does not have any polaririties.
Is there a negative and positive polarities on capacitors?
Electrolytic and tantalum capacitors both have polarity.
Are capacitors polarity sensitive?
The capacitors those are polarity sensitive are called electrolytic and tantalum capacitors. These capacitors are labeled as positive and negative.

Which two types of capacitors are polarized?
Electrolytic and tantalum
What is an unpolarized capacitor?
A capacitor that does not have a designated + and - side. Electrolytic capacitors are usually polarized. Ceramic capacitors are not.
Explained: Electrolytic Motorstart Capacitors?
Falcon Capacitors got a wide range of capacitors manufactured using high-end technology and premium materials. There are tons of options for you to choose from. When it comes to quality and excellence, Falcon capacitors redefine it with its wide range of high-quality capacitors.

What capacitors are polarity sensitive?
While most electrolytic capacitors are the ones that have a polarity noted as minus "-" and "+" as opposed to ceramic or film capacitors, it's important to note that even electrolytic capacitors could also be labelled as "np" for non-polarized or "bp" bi-polarized, which means the same thing, that there is no plus or minus and the current can flow in both directions. Today a good quality electrolytic, most of the time, will be another color to depict this such as green for example, whereas in older circuits they could sometimes look identical but just be missing the little "-" indicator. So, you need to pay attention to this little detail on older boards when replacing a capacitor.

Difference between electrolytic and non-electrolytic capacitors?
Electrolytic Capacitors:1. It provides high capacitance in small volume.2. It has got polarity.3. It is not suitable for high frequencies due to losses in dielectrics.4. It is generally available in 1-100 µF rangeNon-Electrolytic Capacitors:1. Its capacitance depends on dielctric constant of the bulk.2. It doesn't have polarity.3. It is widely used at all frequencies.4. It ranges from pico Farads to fractions of µF.
