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.

BlakeAbsolute permittivity is a measure of a material's ability to store electrical energy in an electric field, while relative permittivity is a ratio of the absolute permittivity of a material to the absolute permittivity of a vacuum. Relative permittivity indicates how well a material can store electrical energy compared to a vacuum.

What is the difference between absolute and gauge pressure?
Absolute pressure is measured relative to a perfect vacuum, while gauge pressure is measured relative to atmospheric pressure.
What is the difference between gauge pressure and absolute pressure?
Gauge pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the pressure measured relative to a perfect vacuum.
What is the difference between gage pressure and absolute pressure?
Gage pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the total pressure including atmospheric pressure.
What is the difference between absolute and relative power?
Absolute power refers to having complete and unrestricted control or authority over a situation or individuals. Relative power, on the other hand, is the comparison of power between different entities or individuals in a particular context, where one party may have more power than another but not necessarily complete control.
Explain the difference between absolute and relative power.?
Absolute power refers to unlimited authority and control over others, often associated with dictatorship or totalitarian regimes. In contrast, relative power is the measure of influence one entity has in comparison to others, taking into account the power dynamics within a specific context or relationship. Relative power is more nuanced and can be influenced by factors such as resources, relationships, and situational dynamics.
