YES IT IS. Any quantity which is ratio of two physical quantities having same unit is dimensionless. Dielectric constant is ratio of Permittivty of medium to the permittivity of free space. As Permittivity of medium and permittivity of free space both have same units(F/m ie Farad/meter) dielectric constant becomes dimensionless quantity

Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
What is dielectric constant?
A dielectric is an insulating material that does not conduct electricity and is transparent to an electromagnetic field. Dielectric materials are used to separate conducting surfaces such as the plates inside a capacitor, wires inside transformers, electric cable conductors, and elsewhere in the electric industry where electrical separation of charged elements is necessary. The dielectric constant is a ratio of the capacitance of a capacitor in which a particular insulating material is the dielectric, to the capacitance of the capacitor in which a vacuum is the dielectric.
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.
If the distance between the parallel plate capacitor is reduced to half and a dielectric of dielectric constant k is introduced then how does electric field varies?
From the formula, E = V/d, where V is the voltage and d is the distance, it can be seen that the electric field and the distance are inversely related. Thus, as the distance between the parallel plate capacitors is reduced to half, the electric field is increased twice. Moreover, is a dielectric constant k is introduced, the capacitance will increase. This direct relationship can be seen in the formula, C = [k(Єo)A]/d, where k is the dielectric constant. The lowest possible value of k is 1; and that is when the dielectric is a vacuum. Other dielectric constants are greater than 1, such as teflon which has a dielectric value of 2.1 As the capacitance increases, the electric field also increases. (E = 1/2(CV^2))
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.
What is meant about di-electric constant?
The dielectric constant (also known as relative permittivity) is a measure of a material's ability to store electrical energy in an electric field. It indicates how much a material can be polarized by an applied electric field. Materials with higher dielectric constants can store more electrical energy and are used in capacitors and insulating materials.
What is relative permitivity?
Relative permittivity, also known as dielectric constant, is a measure of a material's ability to store electrical energy in an electric field. It is defined as the ratio of the permittivity of a substance to the permittivity of a vacuum. Materials with higher relative permittivity can store more electrical energy and are often used in capacitors to increase their capacitance.
What is the unit for the dielectric constant of a medium?
The unit for the dielectric constant of a medium is a dimensionless quantity as it represents the ratio of the permittivity of the medium to the permittivity of a vacuum.
Is relative dielectric constant dimensionless?
Correct: it is a dimensionless number.
How light propagates through a material is given by the ratio of the speed of light in vacuum to the speed of light in that material. What is this ratio called?
That is called the dielectric constant, also the square root of the relative permittivity.
What is relative permittivity of the medium?
Relative permittivity, also known as dielectric constant, is a measure of a medium's ability to store electrical energy in an electric field. It is the ratio of the permittivity of the medium to the permittivity of a vacuum. It influences the capacitance of a capacitor and the speed of electromagnetic waves in the medium.
Why is the dielectric strength of vacuum infinite?
The dielectric strength of vacuum is infinite because there is no molecule in the vacuum.
What is the sodium hypochlorite dielectric constant?
dielectric constant for sodium Hypochlorite
What is dk measurement?
DK measurement is the measurement of the relative dielectric constant of liquids and solid material. It is a measure of permeability.
Dielectric constant of metal is?
The dielectric constant varies, depending on the material.
What happens to a capacitance if the volume is filled with material having a dielectric constant of 5?
The capacitance will increase. When the volume is filled with a material with a dielectric constant greater than 1, the capacitance of the capacitor increases by a factor equal to the material's dielectric constant. This is because the electric field is effectively reduced within the material, allowing more charge to be stored for the same voltage.
