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

Assuming this is about a capacitor: If the dielectric is touching the two plates of the capacitor, the ions even out and the voltage becomes zero. Thus, the capacitor no longer works to store energy.

What happens to the charge of a capacitor when a dielectric slab is fit in it?

Changing the dielectric causes the capacitance to change.


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 the definition of the term dielectric?

'Dielectric' is often used in a general sense to refer to a material (such as ceramic, mica, plastic or paper) which is a poor conductor of electricity. This term is used in the classical description of a capacitor -- two electric conductors separated by a dielectric. By applying electric charge to one conductor an electric field is created. The dielectric allows the electric field to pass through it and affect the other conductors; however the dielectric prevents electrons from flowing between the conductors, so the electric field remains (and the charge remains stored on the conductor). [Side note for beginners: An electric field creates a force (measured in Volts) upon an electron or charged particle which tends to make it move. The conductor allows electrons to move easily within it. The dielectric resists the movement of electrons in it.] More generally, we speak of a 'Dielectric Field' as a mathematic description of how electric charge influences the properties of the space around it. The Dielectric field interacts with space and with any material in the space to create an 'Electric Field'. In simple terms, the electric field at any point is the product of the dielectric field at that point and the 'Dielectric Constant' of the material at that point. In more general terms, the 'electric field vector' at a point is the tensor product of the 'dielectric field vector' and the 'dielectric tensor' of the material at that point. The dielectric field is not a measurable entity, but rather a mathematical tool that allows us accurately to model the electric field, which is measurable. The article on Dielectrics at http://en.wikipedia.org/wiki/Dielectric provides more description, especially on the dielectric field model.


What is dielectric strength?

The dielectric strength refers to the maximum working voltage that a material can withstand without breaking down. At breakdown the electric field frees bound electrons turning the material into a conductor.


What is the difference between conductor and dielectric?

Conductors conduct electricity or heat, energy a Dielectric is essentially an insulator.This has nothing to do with juvenile literature. by the way, waxed paper has a Dielectric of 540,00 Volts per Cubic centimeter, as determined by l909 engineering manuals. I will not reveal how I learned that!


What is function of coaxial?

coaxial cable has a solid copper or copper-clad-steel centre conductor surrounded by a non-conductive dielectric insulating material. The dielectric is surrounded by foil shield/s and/or copper braid/s which form the outer conductor and also shield against electromagnetic interference (EMI). The outer conductor/shield is encased in a PVC jacket.


What happens to Dielectric strength when heated?

it decreases in strength in meany ways for different materials for exsample, with gases if there is an increase in humidity, then it decreases the dielectric strength

If a large enough electric field is applied how does an electric conductor become an insulator?

If a very large electric field is applied on a conductor then a phenomenon of a dielectric breakdown takes place and it looses all its charge carriers to the nearest conductor. Hence becoming an insulator.


Which is the best electrical insulator?

According to a few charts I was able to find, the most realistic material with the highest dielectric strength happens to be Mica, with dielectric strength of 118.
