Does electric flux depend on permittivity?
The electric flux through a surface is defined as the surface integral of the normal component of the electric field through the surface. For closed surfaces, Gauss’s Law states that the electric flux through the surface will only depend on the net charge within the surface, and the permittivity of the medium.
What is permittivity in electric flux?
In other words, permittivity is a measure of how an electric field affects, and is affected by, a dielectric medium. The permittivity of a medium describes how much electric field (more correctly, flux) is ‘generated’ per unit charge in that medium.
How does electric flux vary with dielectric constant?
Therefore, higher dielectric constant means higher relative permittivity which means more resistance to the electric field. But a higher dielectric constant means an increase in electric flux which leads to a higher capacitance!
On which factors electric flux depends?
The numerical value of the electric flux depends on the magnitudes of the electric field and the area, as well as the relative orientation of the area with respect to the direction of the electric field.
Does flux changes with medium?
Yes it does. Magnetic flux is the vector product of the magnetic field and the surface area, and the magnetic field value does change when it passes through different media.
Does the electric field intensity in the space between the plates depend on the permittivity of the medium?
C = \dfrac{Q}{V}. According to (https://en.wikipedia.org/wiki/Capacitor#Parallel-plate_capacitor), the voltage between two plates on the distance d is V = Ed, so if the voltage is constant, the intensity E does not depend on permittivity (but Q does). The electric flux density is.
Does electric flux depend on the size of the Gaussian surface?
Gauss’s law states that net electric flux diverging normally from a closed surface is equal to 1/Eo times the net charge enclosed by the surface that is the electric flux through a closed surface , just depends on the net charge enclosed in the surface and does not depend the shape or size of the surface.
When electric flux is maximum?
The electric flux of a surface is maximum when the area vector is parallel to the direction of the electric field. The electric flux is the total number of lines of force passing through a surface.
What is the relationship between flux and permittivity?
The 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.
What is the relationship between electric flux density and electric field intensity?
It is apparent that the ratio of the electric flux density to the electric field intensity in a point in the field may be understood to be the permittivity of the medium at that point. Let’s assume a parallel plate capacitor having area A, separated by distance d and having permittivity ε for the plate dielectric.
What is absolute permittivity of electric field?
In electromagnetism, absolute permittivity is the measure of the resistance that is encountered when forming an electric field in a medium. In other words, permittivity is a measure of how an electric field affects, and is affected by, a dielectric medium.
How does the permittivity of matter affect Gauss’s law?
The 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.
