# Why do we define electric flux?

Contents

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.

## How would you define electric flux?

Electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. … The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero.

## What is electric flux example?

Flux Definition Physics

We define the Electric Flux as the rate of flow of the electric field through a given area and it varies directly with the number of electric field lines going via a virtual surface. Switch on the mosquito repellent, you smell the fragrance after some time.

## How do you solve electric flux?

Solution: electric flux is defined as the amount of electric field passing through a surface of area A with formula Φ e = E ⃗ ⋅ A ⃗ = E A cos ⁡ θ Phi_e=vec{E} cdot vec{A}=E,A,costheta Φe=E ⋅A =EAcosθ where dot ( ⋅) is the dot product between electric field and area vector and θ is the angle between E and the …

## What is electric flux density?

electric flux density. A measure of the strength of an electric field generated by a free electric charge, corresponding to the number of electric lines of force passing through a given area.

## What is electric field formula?

Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. The formula of electric field is given as; E = F /Q.

## What is electric flux Vedantu?

Hint: We will first discuss the electric field through a given area or the electric field lines through a given virtual surface. … Hence, we can say that the Electric flux is defined as the total number of electric field lines that are passing through a given area in a unit time.

## Is electric flux dependent 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.

## Does electric flux depend on position?

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.
