What is the dielectric constant of cadmium selenide?
10.6
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 are some examples of a chemical property for water?
It has a very high dielectric constant
Why do polar substance have a high dielectric constant?
Water, due to its polar nature, has a large dielectric constant. Therefore, water molecule has a very large electric dipole moment and is forced to rotate to respond to an alternate external electric field. Hence water as a liquid has a very large dielectric constant i.e. 80. Mica on the other hand is less polar as water and hence has low dielectric constant.
What is the relation between Dipole moment and Dielectric constant?
The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability. As the dielectric constant increases, the electric flux density increases, if all other factors remain unchanged. This enables objects of a given size, such as sets of metal plates, to hold their electric charge for long periods of time, and/or to hold large quantities of charge. Materials with high dielectric constants are useful in the manufacture of high-value capacitors.
What is dielectric constant in chemical terms?
dielectric constant
What is the sodium hypochlorite dielectric constant?
dielectric constant for sodium Hypochlorite
Dielectric constant of metal is?
The dielectric constant varies, depending on the material.
What is relative permittivity if dielectric constant of water is 80.10?
'Dielectric constant' is an archaic term for relative permittivity. They are one and the same.
Why does dielectric constant decrease with an increase in temperature?
If the temperature increases, the conductivity will increase too which means the dielectric constant is reduced
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
What is the Electric field inside a Dielectric?
E = Eo/k k is dielectric constant
What is the dielectric constant of cadmium selenide?
10.6
What is dielectric constant of a metal?
It can be taken as infinity
Can the dielectric constant of carbon in water be measured?
dielectric constant is a property of a material, this question is asking the property of a two mixed together, in an undeclared ratio. But yes dielectric constants can be measured. The problem you will have is keeping a uniform mix.
How capacitor is used to check freshness of fish?
Between the two plates of a capacitor lies a medium with a specific dielectric constant. Placing a fish between these plates changes to dielectric constant. If the fish is fresh it will be strong and tight, thus possessing a higher dielectric constant. If the fish is older, it's dielectric constant, or body, will be weaker due to decay.
