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 the significance of the permittivity of a material, denoted by the symbol epsilon r, in the context of electrical engineering?
The permittivity of a material, represented by the symbol epsilon r, is important in electrical engineering because it determines how well a material can store electrical energy and how it interacts with electric fields. Materials with higher permittivity can store more electrical energy and are often used in capacitors and other electronic components to control the flow of electricity.
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.
What is the value of relative permittivity of wood?
The relative permittivity of wood typically ranges from 2-3. This means that wood is a relatively poor electrical insulator compared to materials with higher relative permittivity values.
What is relative permittivity of pure conductor?
The relative permittivity of a pure conductor is infinite. This is because in a pure conductor, electrons are free to move, resulting in a strong response to electric fields, leading to an infinite value for its relative permittivity.

What is Relative dielectric constant for vacuum?
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
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.
Do relative permittivity and dielectric constant of a medium imply different physical qantities?
Relative permittivity and dielectric constant are often used interchangeably, but they can imply different contexts. Relative permittivity (ε_r) is a dimensionless measure of a material's ability to store electrical energy in an electric field, relative to the vacuum. The term "dielectric constant" traditionally refers to this same quantity, but it can sometimes be used more loosely to describe the material's overall insulating properties. Thus, while they represent similar concepts, the terminology can depend on the specific physical context being discussed.
What is relative permittivity of pure conductor?

Why relative permittivity of germanium is greater than that of diamond give reason?
The relative permittivity of a material is a measure of how much the material can store electric potential energy. Germanium has a higher relative permittivity than diamond because germanium has more free charge carriers (due to its intrinsic semiconductor properties) that can contribute to the overall permittivity. In contrast, diamond is a pure covalent material with no free charge carriers, resulting in a lower relative permittivity.
