What is the capacitor and how many types?
A capacitor is a circuit component that stores energy in the electric field set up between its plates.Capacitors are named after the dielectric used to separate their plates (e.g. 'mica' capacitor), and there are lots of different types of dielectric used (too many to list), so there are a corresponding number of types of capacitor.But you can also categorise a capacitor as being 'polarised' or 'non-polarised'; electrolytic capacitors are 'polarised', which means that they must be connected into a circuit while taking into account the polarity of their terminals.Finally, you can categorise them as being 'fixed value' or 'variable'.
How capacitor is connected in a table fan?
The Capacitor with running winding is connected in parallel with main winding.
How do you flow current in capacitor through dielectric?
well actually current doesn't exactly pass through the capacitor or dielectric.Current just flows through the wires connected to the capacitor.The reason is that electric charges are only placed onto capacitor plates and they flow in the circuit and it seems to us that current is flowing in the circuit.Also remember that dielectric only increases the capacitance of a capacitor.AnswerThere are two types of electric current, termed 'conduction current' and 'displacement current', respectively.A 'conduction current' describes the drift of free electrons in a metal conductor. A 'displacement current' describes the polarisation of atoms in dielectrics.When an electric field is applied to a dielectric, the elliptical orbits of the electrons around each atom's nucleus become distorted, and stretch, resulting in polarised atoms. The amount of 'stretch' (polarisation) increases with the strength of the electric field. So, as the voltage across the changes so, too, does the amount of polarisation -i.e. so, too, does the displacement current.So when a capacitor is connected to an external d.c. supply, a varying conduction current drifts around the circuit conductor, while a displacement current occurs within the capacitor's dielectric. When a capacitor is connected to an external a.c. supply, a continuously varying potential difference results in a continuously changing conduction current in the metallic circuit, and a continuously changing displacement current within the capacitor's dielectric.
What type of electrolytic capacitor will be permanently damaged if connected to the incorrect polarity?
A polarized capacitor will be permanently damaged if connected to the incorrect polarity.
How can electricity be stored?
In a way it can be. If a capacitor is connected to a battery, it will charge to the battery voltage. Then the capacitor can be discharged into a circuit to do work. But the capacitor doesn't store electrons, it stores an electrical field in the dielectric. If you mean storing the flowing electrons in a conductor, then they can't be stored except in a magnetic containment field such as in a cyclotron. A rechargable battery doesn't store electrons either, it stores energy in a chemical form which is converted to an electrical form when the battery is connected to a circuit.
What are the two parts for a variable capacitors?
The main parts of a capacitor are:two conducting plates separated byan insulating material (called a dielectric) surrounded byfurther insulation - plastic or paper - as a protective jacket andexternal wires (connected internally to the plates) to allow the capacitor to be connected into a circuitand, on large units:a protective case made of metal or plastic andexternal terminals connected internally to the plates,to allow the capacitor to be connected into a circuit.

Which Capacitor should be connected in one direction?
The electrolytic capacitor should be connected in only one direction.
Why capacitor is connected to earth in circuit?
when a capacitor is connected to earth the potential of capacitor becomes zero. as a result all the charge residing on the conductors of a capacitor passes away and the final charge on capacitor becomes zero
What is the part of capacitor?
Capacitors consist of a insulating material, called a 'dielectric', sandwiched between two conductors, called 'plates'. Capacitors are devices that store energy(not charge!); this energy is stored in the electric field set up within the dielectric between the two plates when they are connected to an external potential difference.
Why capacitor burst?
Electrolytic capacitors tend to explode when connected to AC or to DC currents of the wrong polarity. The plates short out because the dielectric is maintained by a polarized field, and is then destroyed by the wrong polarity.
What type of electrolytic capacitor will be permanently damaged if connected to the incorrect polarity?
A polarized capacitor will be permanently damaged if connected to the incorrect polarity.

How do you wire a capacitor to an amp?
Positive post of capacitor is connected to the heavy amp cable. The ground terminal (or case) of the capacitor is connected to the car's ground or a ground wire that leads to the car's chassis. That's it.
