A capacitor is an electronic device for accumulating and holding a charge of electricity. It consists of two equally charged conducting surfaces having opposite electrical polarity which are separated by a dialectric insulator.
It is a passive electronic component that stores energy in the form of an electrostatic field.
Another Answer
A capacitor is a circuit component that stores energy. It consists of two, parallel, conducting surfaces, called 'plates', separated by an insulator or dielectric. When attached to a d.c. supply, negative charges are transferred from one plate to the other and, if it is then removed from the d.c. supply, the one plate remains negative with respect to the other.
It's a misconception to say that a capacitor 'stores charge', because the amount of charge on the plates remains the same before and after 'charging'! It is more accurate to say that it stores 'separated charges' but, strictly speaking, it's energy that's being stored.

What will happen if you changes the polarity of the capacitor in their respective position?
It will either explode right away, or work for a short time then explode. Note though, that the capacitor's polarity only applies to DC voltage. Because AC flows through a capacitor, if there is no DC offset, it matters not which way the capacitor goes.
How does an electret microphone work?
The electret microphone is based on the electret capacitor, which is a special capacitor with quasi-permanent charge. Vibrations in the air are picked up by the capacitor, which generates an equivalent vibrating electrical signal. Unlike a traditional condensor (another name for capacitor) microphone, the electret does not require a power source.
What is the purpose of capacitor in power supply higher than rated voltage?
The voltage marked on a capacitor is its MAXIMUM SAFE WORKING VOLTAGE. The capacitor will work in a circuit at any voltage lower than that, but it may fail at any higher voltage.
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.

What if your washing machine capacitor does not work?
YES THERE ARE TWO (2): 1. STARTING CAPACITOR 2. RUNNING CAPACITOR
How much uranium can the flux capacitor hold?
The flux capacitor is now only a phantasy. Flux capacitor will not work with Uranium. It has to be Plutonium.
Can capacitor work in dc?
Yes.
Can you replace 1.7 microFarad capacitor with 2 microFarad capacitor of capacitor start motor?
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
Can you replace a 135D capacitor with a 138D capacitor?
its only three different so.......it should work! i think...
Effect of shorting out the capacitor in a clamping circuit?
Any circuit using a capacitor will not work if the cap is short-circuited.
What is the work of capacitor in sodium vapour lamp?
A sodium vapour lamp does not include a capacitor in its construction. Any capacitor associated with this type of fixture will be found where the ballast is located and not in the lamp itself.
Does the flux capacitor really work?
No, it only works "in the movies".
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.
How does an ac curcuit work if current cant flow through a capacitor?
AC current can flow through a capacitor, it's DC current that can't
Will capacitor run motor work on windmill?
No , it only for reducing the reactive power and at the time of motering mode for that purposre only we are using capacitor in wind mill
