# Best answer: What is electric flux and its SI unit and dimension?

Contents

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 its unit and dimension?

Electric Flux: Electric flux is a number of electric lines of forces which posses through any cross sectional area when the cross sectional area in kept perpendicular to the direction of electric field. Electric flux is scalar quantity which is denoted by ΦE​. S.I. Unit is Neutron(metre2/ coulomb) NM˙2/C.

## What is electric flux and SI unit?

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

## What is electric flux write its dimension?

Electric flux is defined as the measure of count of number of electric field lines crossing an area. Electric flux ϕ=EAcosθ SI unit of electric flux is Nm2/C.

## What is called 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 Ncert?

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.

## What is flux in chemistry class 12?

Flux is the substance added during the extraction of metals. On heating it reacts with the earthly impurities(gangue) to form fusible (molten) mass known as slag. They may be acidic or basic in nature. Acidic flux are is used to remove the basic impurities. For example silica.

## What’s the unit of flux?

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.

## What is the unit of electric flux in CGS system?

The CGS unit of magnetic flux is Maxwell (Mx) or Abweber (abWb). The fundamental unit of magnetic flux is Volt-seconds.

Submultiples of Weber(Wb)

## What is the SI unit of electric current?

Unit of electric current: ampere (A)

THIS IS UNIQUE:  What energy sources does Austria use?

The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 ×1019 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆νCs.

## What is the SI unit of electric flux density?

The SI unit of electric flux density is \$dfrac{C}{{{m}^{2}}}\$ it can also be written as \$dfrac{N}{C}\$ . So, the correct answer is “Option A”. Note: When the field lines are perpendicular to the surface of the body the electric flux density of the body is zero.
