The permittivity of free space
Webb13 nov. 2024 · The physical constant $\epsilon_0$ is usually called "permittivity of free space" or "vacuum permittivity". Griffiths says: I dislike the term, for it suggests that the vacuum is just a special kind of linear dielectric, in which the permittivity happens to have the value $8.85 \space 10^{-12}\space \rm {C^2\over Nm^2}$. But later on, in a … WebbPhysics. Physics questions and answers.

Webb2 okt. 2016 · If the square root is taken of the magnetic permeability constant divided by the electrical permittivity constant ($\epsilon_0$),the result is 377 $Ω$. (The units work out to ohms after some manipulations). I find it extremely intriguing that free space, i.e. outer space, has an electrical resistivity. WebbThe permittivity of a medium describes how much electric field (more correctly, flux) is 'generated' per unit charge in that medium. It is clear that more the permittivity of a matter, more resistance is offered to the electric field resulting in decrease if the flux in Gauss law. In other words Flux in inversely proportional to permittivity.
