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 material?
A dielectric material is a substance that is a poor conductor of electricity, but an efficient supporter of electrostatic fields
What happens to a capacitance if the volume is filled with material having a dielectric constant of 5?
Compared to a vacuum (dieletric constant = 1), or air (dielectric constant is close to 1), the capacitance will be five times as great in this case (other things being equal).
What is the unit of dielectric strength?
In SI, the unit of dielectric strength is volts per meter (V/m). In U.S. customary units, dielectric strength is often specified in volts per mil.In physics, dielectric strength 2 meanings:Of an insulating material, the maximum electric field that a pure material can withstand under ideal conditions without breaking down.For a specific configuration of dielectric material and electrodes, the minimum applied electric field that results in breakdown.
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.

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 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 separates terminals inside a capacitor?
Any dielectric material can be used to separate the two metal plates inside a capacitor. This includes polymer, paper, glass or even air (although air is seldom used now).
For an insulating material dielectric strength and dielectric loss should be what?
high and high
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
What is the dielectric?
Insulation property of a material
Dielectric constant of metal is?
The dielectric constant varies, depending on the material.
What is meant about di-electric constant?
The relative permittivity of a material is its dielectric permittivity expressed as a ratio relative to the permittivity of vacuum.Permittivity is a material property that expresses the force between two point charges in the material. Relative permittivity is the factor by which the electric field between the charges is decreased or increased relative to vacuum.Likewise, relative permittivity is the ratio of the capacitance of a capacitor using that material as a dielectric, compared to a similar capacitor that has vacuum as its dielectric. Relative permittivity is also commonly known as dielectric constant, a term deprecated in physics and engineering.
What is the fill material in the run capacitor?
Plastic 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.
