# What does electric flux depend upon?

Contents

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. … , demonstrating that electric flux is a measure of the number of field lines crossing a surface.

## Does flux depend on medium?

Yes, the medium affect the electric flux. Vacuum permitivity relates the relative effect against that of an ideal vacuum.

## Why does electric flux depend on medium?

Well it more that electric flux density is dependent on the medium properties to which an inducing electric field is applied. All mediums / materials , including free space, have an absolute permittivity which indicates all are able to realise an electric flux density when subject to an inducing electric field.

## Does electric flux depend on position of charge?

As long as the amount of charge inside the surface stays the same, the total electric flux through the surface does not depend on where the charge is located. It also doesn’t depend on the size or shape of the surface, so long as the surface is closed.

## Does electric flux depends upon shape?

As per the Guess theorem in electrostatics, electric flux does not depend on the shape or size of the surface. The electric flux depends only on the charge enclosed by the surface.

## Does flux depend on permittivity?

From Equation [3], the Electric Flux Density is very similar to the Electric Field, but does not depend on the material in which we are measuring (that is, it does not depend on the permittivity . Note that the D field is a vector field, which means that at every point in space it has a magnitude and direction.

## Does Gauss law depend on medium?

No Gauss law is applicable for any type of electric field. If the field is symmetrical then some easy and know surface can be used as Gaussian surface. For example consider electric field due to a point charge. The field is symmetrical and so you can take a sphere as Gaussian surface this makes the problem easier.

## Does electric flux depend on radius?

Gauss’s Law

– The total electric flux through any closed surface is proportional to the total electric charge inside the surface. Point Charge Inside a Spherical Surface: – The flux is independent of the radius R of the sphere.

## Does electric flux depend on nature of surface?

Gauss’s law of electricity, which is included within the fundamental laws of electromagnetism, states that the electric flux through a closed surface with electric charge inside, just depends on the net charge enclosed in the surface and does not depend the shape or size of the surface.

## How does electric flux depend on area?

it’s like the electric field is inversely proportional to the applied surface area of the enclosing surface area. The flux through a closed (Gaussian) surface depends on the net charge enclosed by the surface, according to Gauss’s law. The shape and size of the surface does not change the flux.

## Can flux be negative?

The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. If a net charge is contained inside a closed surface, the total flux through the surface is proportional to the enclosed charge, positive if it is positive, negative if it is negative.

## How is electric flux calculated?

The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field.
