What is difference between absolute permittivity and relative permittivity of medium?
The absolute permittivity of a medium is its relative permittivity multiplied by the vacuum permittivity. The absolute permittivity is a proportionality constant between the electric and displacement field with units of Farad/meters (in SI units). This number is usually very small (e.g. for air: 0.000 000 000 008 85 F/m). The relative permittivity is a unit-less number scaled upward to present nicer numbers (e.g. for air: 1.0005). To get the absolute permittivity from the relative permittivity one should multiply with the vacuum permittivity: 8.85418781... E-12 F/m.
What is permittivity of diamond?
According to Wikipedia, below, the relative permittivity of diamond is 5.5-10, given that:"The relative permittivity of a material under given conditions reflects the extent to which it concentrates electrostatic lines of flux. In technical terms, it is the ratio of the amount of electrical energy stored in a material by an applied voltage, relative to that stored in a vacuum. Likewise, it is also the ratio of the capacitance of a capacitor using that material as a dielectric, compared to a similar capacitor that has a vacuum as its dielectric."
What is the value of epsilon in physics?
epsilon generally tends towards zero. if you mean the relative permittivity epsilonr it is material dependent
Is water an insulator or conductor?
Pure water (distilled water) is an insulator. Generally we think of water as a conductor because there are impurity ions in the water, such as tap water. Pure water can't be called a conductor, but it can also conduct electricity.
Is bronze a conductor or insulator?
It is a conductor. Alloys like bronze are generally not as good at conducting electricity as pure metals.
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 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.

Is pure water an electrical conductor?
At a high enough voltage, everything is an electrical conductor. Pure water is an exceptionally bad electrical conductor, though.
Is pure water is a conductor or insulator?
pure water is an insulator.
Is gold a better conductor than germanium?
Yes. Pure gold is a much better conductor than pure germanium is.
What determines the strength of a magnetic field?
factors on which magnetic field a bar magnet depends :- 1. pole strength of the magnet 2. medium in which the bar magnet is present(since the permittivity changes) factors on which external magnetic field(B) of a current carrying coil depends:- 1. the amount of current flowing through the conductor 2. the perpendicular distance of the point from the conductor. 3. medium in which the conductor is present(since the permittivity changes)
What is the conductor of elec tricity?
