# What size is electric flux?

Contents

Therefore, the electric flux is dimensionally represented as [M1 L3 T-3 I-1].

## What is the size unit of electric flux?

2. What is SI unit of Electric Flux? Ans. Electrical flux has SI units of volt meters (V m), or, evenly, Newton meters squared per coulomb (N m2 C1).

## Does electric flux depend on size?

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.

## How do you measure electric flux?

The unit of electric field is Vm.

1. Hence dimension of electric field is [MLT−3I−1]
2. The electric flux is given in unit Nm2C−1.
3. Hence dimension of electric flux is [ML3T−3I−1]

## 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 electric flux Class 12?

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. … The vector associated with every area element of a closed surface is taken to be in the direction of the outward normal.

## What is the unit of electric flux Class 12?

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.

## Why electric flux is independent of shape and size?

The electric flux through a closed surface (see Gauss’s Law ), such as a sphere, is independent of area because as the closed surface becomes larger the electric field will become weaker but applied over a larger area, but the resulting electric flux will be the same as the electric flux through a smaller closed …

## Does the size and shape of container can affect the flux?

(c) The shape and size of the surfaces that enclose a charge does not matter because all surfaces enclosing the same charge have the same flux.

## What is the electric flux through the upper face of the box?

The electric flux through the top face (FGHK) is positive, because the electric field and the normal are in the same direction. The electric flux through the other faces is zero, since the electric field is perpendicular to the normal vectors of those faces.

[M1L2T−1A−2]

## Can the electric flux through A surface is zero?

Gauss’s law tells us that the electric flux through a closed surface is proportional to the net charge enclosed by the surface. Thus, the electric flux through the closed surface is zero only when the net charge enclosed by the surface is zero.

## What is the electric flux through A cube of side 1 cm which encloses an electric dipole?

Direction from -q to q is dipole direction. Therefore the net charge enclosed within the cube is 0 . i.e. Q = 0. Hence, the electric flux through the cube is 0.

## What is meant by electric flux explain it giving formula?

Electric Flux Formula

The total number of electric field lines passing a given area in a unit time is defined as the electric flux. Similar to the example above, if the plane is normal to the flow of the electric field, the total flux is given as: ϕp=EA.

## What is the electric flux due to electric field E 3 * 10 3?

electric flux will be zero.

electric field, E = 3 × 10³ i N/C through a square of side 10cm.

## What is electric flux write the expression for electric flux?

If the electric field is uniform, the electric flux passing through a surface of vector area S is ΦE=E⋅S=EScosθ Φ E = E ⋅ S = ES cos ⁡ .
