# You asked: What is electric flux density and electric field intensity?

Contents

Electric flux density, assigned the symbol D, is an alternative to electric field intensity (E) as a way to quantify an electric field. … The electric flux density D=ϵE, having units of C/m2, is a description of the electric field in terms of flux, as opposed to force or change in electric potential.

## What is relation between electric flux density and field intensity?

The electric flux through an area is defined as the number of electric field lines passing through that area normally. If the electric field at a certain point be →E . Then, the electric flux through an infinitesimal area with an area vector d→S d S → around that point will be given by: dϕ=→E⋅d→S d ϕ = E → ⋅ d S → .

## What is the difference between electric flux and electric field intensity?

The electric field intensity of a point inside the electric field of a charge is the force experienced by a unit positive charge (+1 coulomb) placed at that point. It is a vector quantity having unit N/C. … The number of electric lines of force passing through an area held perpendicularly is called electric flux.

## What is electrical 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 the unit of electric field intensity and electric flux density?

Electric flux has SI units of volt meters (V m), or, equivalently, newton meters squared per coulomb (N m2 C1). Thus, the SI base units of electric flux are kg·m3·s3·A1.

## 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.
