How are capacitors made?
A capacitor, in its simplest form, is two conductive plates separated by a dielectric.
What are the three factors that determine the charge of a capacitor?
If you mean the capacity of the capacitor then, Factors are:- Area of of overlap of the plates Separation of the plates How good is the insulating material between the plates (the dielectric) If you mean how large a charge can be stored then, Factors are:- The capacitance of the capacitor (C). The applied voltage (V). Charge Q =CxV V cannot exceed the dielectric's breakdown voltage.
On what factors capacitance of a capacitor depends on?
The job of a capacitor is to store charge onto its plates. The amount of electrical charge that a capacitor can store on its plates is known as its Capacitance value and depends upon three main factors.The surface area, A of the two conductive plates which make up the capacitor, the larger the area the greater the capacitance.The distance, d between the two plates, the smaller the distance the greater the capacitance.The type of material which separates the two plates called the "dielectric", the higher the permittivity of the dielectric the greater the capacitance.
An air-filled parallel-plate capacitor is connected to a battery and allowed to charge up Now a slab of dielectric material is placed between the plates of the capacitor while the capacitor is still?
the charge on the capacitor had increased.
What is a capacitor and how does it work?
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 AnswerA 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.passive two-terminal electrical component used to store energy electrostatically in an electric field this is an instrument that is used to store chargecapasitor is electronic device his work useful for electronic gadjet and also useful electronic machine ther are six type of capasitor ceramic capasitor:"electrolightic capasitor:"plastic film rasistor:"polishtor film rasistor:"propfylin capasitor:"metalesed capasitor
If you take out the battery in a capacitor before inserting a dielectric will there still be charge on the dielectric?
The charge in a capacitor is between the plates. The dielectric is only an insulator that allows the plates to be very close without touching and discharging the charge. There is no battery in a capacitor.
How are capacitors made?

What makes the capacitor to store charges?
A capacitor consists of two plates (foils ...) separated by an insulating medium. The insulating medium may be air, oil, a plastic film, and so on, and is known as the dielectric. The charge on the capacitor is actually stored by slightly distorting the molecules in the dielectric. The quality of a dielectric is measured by a factor known as K, and a higher K means that the molecule can store a larger distortion. When we discharge the capacitor, the molecules are allowed to relax to their uncharged state.
What are the functions of capicitor?
A capacitor is essentially a device that develops and stores an electric charge along a circuit. It consists of two conductive plates spaced a particular distance apart, with a material known as a dielectric between them.

What is an Air dielectric capacitor?
Capacitors are, in principal, two parallel plates separated by something (the dielectric). This dielectric can be many things, in fact most non-conductive things, air is just one. Warning, heavy science (way way above my level) http://en.wikipedia.org/wiki/Dielectric#Some_practical_dielectrics Photo of variable air dielectric capacitor, used to be used to tune radios for example. You can see the plates and air gap. http://en.wikipedia.org/wiki/File:Variable_Capacitor.jpg G
What are the factor affecting capacitances of capacitance?
The area of the sheets, the distance between them, and the material between them.
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.

the charge on the capacitor had increased.
What happens when dielectric breakdown occurs?
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
What is space charge?
When a dielectric ( insulator) is kept between the two plates of a charged condenser, the atoms or molecules are polarised due to shifting of + nucleus towards negative plate and negative electrons towards positive plate of the condenser. Naturally, any dielectric contains certain defects like grain boundaries, voids, dislocations etc. The migrating charges accumulate at these sites creating additional polarization. This polarization is called space charge polarization. The charges accumulate at the interfaces of the dielectric and condenser plates is called inter-facial polarization, is also one kind of space charge polarization.
