# On what factors does electric flux depends?

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.

## 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 electric 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 flux depend on position of charge?

If you consider the the total electric flux through a closed surface, it depends only on the total charge enclosed by the surface. The total flux is insensitive to the exact location of the charge within the surface.

## Is flux dependent on area?

The total flux depends on strength of the field, the size of the surface area it passes through, and on how the area is oriented with respect to the field. You can think of flux as the amount of something crossing a surface.

## 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.

## 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.

## 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.

## What is flux density formula?

Flux density is simply the total flux divided by the cross sectional area of the part through which it flows – B = Φ / Ae teslas. Thus 1 weber per square metre = 1 tesla. Flux density is related to field strength via the permeability. B = μ × H.

## What happens to flux density when charge increases?

The expression for flux density is: D=Q/A. Electric flux is directly proportional to charge, hence as charge increases, electric flux also increases. … Electric flux is inversely proportional to area, hence an area increases, electric flux decreases.
