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.
Function of dielectric in a capacitor?
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
What is the fill material in a run capacitor?
Plastic dielectric
Which consists of two plates separated by a dielectric and can store a charge?
Capacitor
How are capacitors made?
A capacitor, in its simplest form, is two conductive plates separated by a dielectric.
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.

When excessive voltage is applied to a capacitor it will break down What factor of the capacitor has the greatest effect on breakdown voltage?
The dielectric material between the plates.
What is the term for the flow of electrons through the insulating material of a capacitor?
The term for the flow of electrons through the insulating material of a capacitor is called "dielectric breakdown."
What is the potential difference across each capacitor when the plate separation is doubled?
When the plate separation of a capacitor is doubled, the potential difference across each capacitor remains the same.
A capacitor is a device which stores energy by?
Magic. Look up capacitors on wikipedia!!A capacitor stores electrical charges in its plates.Both wrong. A capacitor stores energy as an electric field developed in the dielectric between its plates. A good dielectric with high permittivity (once called dielectric constant) concentrates this field, allowing more energy to be stored in a capacitor having the same plate area and separation but a dielectric of lower permittivity.
What is definition of paper capacitor?
A paper capacitor is a type of capacitor that uses paper as the dielectric material between its conductive plates. The paper is impregnated with a dielectric such as oil or wax to improve its insulation properties and prevent breakdown. Paper capacitors are low-cost, reliable, and suitable for use in low-voltage applications.
How do capacitors classified?
capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.
What happens when dielectric is a conductor?
Yes possible. As a capacitor even with air as dielectric allows alternating current to pass through the capacitor filled with some material as dielectric would allow current to pass through it
What is the material use in the capacitor?
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
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.
What happens to charge and potential difference and capacitance in the presence of dielectric when the battery is disconnected from the capacitors?
The capacitor will hold the charge, until it leaks off due to resistances in the dielectric or external.
