Dielectric heating is a type of heating used in engineering. Insulated materials are heated and then put over an electric field that changes quickly. It is usually used for making plastics and rubber.

What is the Electric field inside a Dielectric?
E = Eo/k k is dielectric constant
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 is electrical grease?
dielectric grease.
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 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.
What is thermal loss in dielectric heating?
Thermal loss in dielectric heating
What is dielectic heating?
Dielectric heating, also known as electronic heating, RF (radio frequency) heating, and high-frequencyheating, is the process in which a high-frequency alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material.
What is the advantages of dielectric heating?
a major advantage of this form of heating is the ability to repadily heat throughout the volume
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.

For an insulating material dielectric strength and dielectric loss should be respectively?
For an insulating material dielectric strength and dielectric loss should be respectively
What is dielectric constant in chemical terms?
dielectric constant
For an insulating material dielectric strength and dielectric loss should be respectively high or low?
For an insulating material dielectric strength and dielectric loss should be respectively high or low
What is dielectric test in transformer?
why need dielectric test for transformer
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.
What is the sodium hypochlorite dielectric constant?
dielectric constant for sodium Hypochlorite
What is leaky dielectric?
A leaky dielectric is a poorly conducting liquid. Refer to "ELECTROHYDRODYNAMICS: The Taylor-Melcher Leaky Dielectric Model" for more information.
