Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
Where is the knowledge of dielectric strength helpful?
One field in which this is helpful is in the manufacture of insulating materials. Dielectric strength determines the strongest electric field an insulator can withstand before it fails. For example, if the insulation around a wire melts or breaks, the insulator's dielectric strength is compromised.
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.
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 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.
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
For an insulating material dielectric strength and dielectric loss should be what?

What does dielectric strength mean?
Of an insulating material, the maximum electric field strength that it can withstand intrinsically without breaking down, i.e., without experiencing failure of its insulating properties.
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.
Which is another name for dielectric strength test?
ASTM D149 - 09 Standard Test Method for Dielectric Breakdown Voltage and Dielectric Strength of Solid Electrical Insulating Materials at Commercial Power Frequencies
What do you mean by dielectric and name any five materials used as dielectrics?
A 'dielectric' describes a material that supports an electric field and is generally used to describe an insulating material. Two properties exhibited by a dielectric are its permittivity and its dielectric strength. High values of permittivity (abillity to improve capacitance) are desirable for dielectrics used in capacitors, and high values of dielectric strength (ability to withstand voltages) are desirable for insulators but, unfortunately, the two quantities aren't relatated. So, selecting a dielectric is a matter of compromise.
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.

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.
Difference between insulation resistance and dielectric strength?
INSULATION RESISTANCE: The insulation resistance is a measure of the capability of a material to withstand leakage of current under a Vdc potential gradient. DIELECTRIC STRENGTH: The dielectric strength is a measure of the ability of the material to withstand a large field strength without electrical breakdown, and is usually expressed in volts per mil (.001') or volts per cm of dielectric.
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.
Where does static electricity occur?
when 2 bodies are rubbed together,electrons are transferred this causes static electricity.
