# What is electric flux due to dipole?

Contents

The electric flux of a dipole is equal to zero.

## What is the electric flux due to dipole in an enclosed sphere?

flux (phi) = Q(enclosed)/epsilon. that means that the net electric flux is dependent on the net charge enclosed by the closed surface. for an electric dipole since the net charge enclosed is zero, hence the net flux is obtained to be zero. therefore the net flux is zero !

## What is the flux due to electric field?

In electromagnetism, electric flux is the measure of the electric field through a given surface, although an electric field in itself cannot flow. It is a way of describing the electric field strength at any distance from the charge causing the field.

## What is the relation between electric flux and dipole moment?

An electric dipole in an external electric field is subjected to a torque τ = pE sin θ, where θ is the angle between p and E. The torque tends to align the dipole moment p in the direction of E. The potential energy of the dipole is given by Ue = −pE cos θ, or in vector notation Ue = −p · E.

## Does electric flux depend on 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.

## What happens when an electric dipole is kept at the Centre of a sphere?

So, if an electric dipole is placed inside the sphere then the flux coming out from electric field lines of positive charge will be equal to the flux going out from electric field lines of negative charge. Therefore, electric flux entering into the sphere is equal to electric flux leaving from the sphere.

## What do you mean by electric dipole moment?

The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system, that is, a measure of the system’s overall polarity.

## What is the flux through the cube?

According to gauss law, the electric flux through a closed surface is equal to qε∘ , if q is the charge enclosed in it. If the charge ‘q ‘is placed at one of the corners of the cube, it will be divided into 8 such cubes. Therefore, electric flux through the one cube is the eighth part of qε∘

## 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.

## Can electric field be negative?

Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
