# What is meant by electric flux?

Contents

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 and its unit?

Electric flux – Electric flux is the measure of number of electric field lines passing through any surface . It is a scalar quantity. It’s S.I unit is volt meters. Gauss Law- It is defined as the total flux linked within a closed surface is equal to the 1ε0 times the total charge enclosed by that surface.

## What is electric flux class 12th?

Electric flux is the measure of flow of the electric field through a given area. Electric flux is proportional to the number of electric field lines going through a normally perpendicular surface. … Unit of electric flux is NC1m2.

## What is meant by flux in physics?

Flux describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance. … In vector calculus flux is a scalar quantity, defined as the surface integral of the perpendicular component of a vector field over a surface.

## What is flux in physics class 11?

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.

## 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 called electric dipole give an example?

An electric dipole is defined as a couple of opposite charges q and –q separated by a distance d. … The midpoint q and –q is called the centre of the dipole. The simplest example of an electric dipole is a pair of electric charges of two opposite signs and equal magnitude separated by distance.

## What is flux with example?

Flux is a chemical purifying agent, flowing agent or cleaning agent. Most commonly, it is used in metal joining and metallurgy. Some examples of flux include: Ammonium chloride. Zinc chloride.

## What is flux and its types?

It is the substance added to molten metals to bond with impurities that can be readily removed. Types of flux: Fluxes are of two types, viz, acidic flux and basic flux. (a) Acidic flux: It is an acidic oxide (oxide of a non-metal) like SiO2, P2O5, B2O3 (from borax).

## 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 is the SI unit of Weber?

Weber, unit of magnetic flux in the International System of Units (SI), defined as the amount of flux that, linking an electrical circuit of one turn (one loop of wire), produces in it an electromotive force of one volt as the flux is reduced to zero at a uniform rate in one second.
