What is the flux through a closed surface?

1. The net flux through a closed surface is a quantitative measure of the net charge inside a closed surface. 2. The net electric flux through any closed surface surrounding a net charge ‘q’ is independent of the shape of the surface.

What is equipotential surface Quora?

Answered 1 year ago · Author has 53 answers and 170.1K answer views. “Equipotential surface”: The Equipotential surface is the imaginary surface in an electric field on which the value of electric potential is same at all the points of it. The shape of equipotential surface are different in different electric field.

What is the net electric flux through the closed surface that surrounds the conductor?

The net electric flux through a closed surface that surrounds no charge is zero.

When can you use Gauss law?

Gauss’s law is usually used in cases of symmetry (spherical/cylindrical/planar) where we could determine that the electric field on a closed loop is constant on every point of it (dependent only on r) and fom there we could get it out of the integral.

Is Gauss always applicable?

No Gauss law is applicable for any type of electric field. If the field is symmetrical then some easy and know surface can be used as Gaussian surface. For example consider electric field due to a point charge.

What is equipotential and surface?

An equipotential line is a line along which the electric potential is constant. An equipotential surface is a three-dimensional version of equipotential lines. Equipotential lines are always perpendicular to electric field lines.

What is meant by the equipotential surface?

The surface which is the locus of all points which are at the same potential is known as the equipotential surface. In other words, any surface with the same electric potential at every point is termed as an equipotential surface.

What is the total electric flux through a closed surface containing a 2.0 ΜC charge?

What is the total electric flux through a closed surface containing a 2.0 μC charge? Φ = q ε 0 = 2 ⋅ 1 0 − 6 8.85 ⋅ 1 0 − 12 = 0.23 M W b .

What is the net electric flux through the box?

– The net electric flux through the surface of a box is directly proportional to the magnitude of the net charge enclosed by the box. →net flux constant. -The net electric flux due to a point charge inside a box is independent of box’s size, only depends on net amount of charge enclosed.

Why is Gauss law not useful?

No Gauss law is applicable for any type of electric field. If the field is symmetrical then some easy and know surface can be used as Gaussian surface. For example consider electric field due to a point charge. The field is symmetrical and so you can take a sphere as Gaussian surface this makes the problem easier.

What is the net electric flux through a closed surface?

Gauss law: The electric flux passing through any closed surface is equal to the total charge enclosed by the surface. Charge is outside the closed surface. The no of flux entering the closed surface is also leaving it. So net flux through the closed surface is zero Why is an electric flux through a closed surface independent of area?

What is the electric flux of a non-uniform electric field?

Flux of a Non-uniform Electric Field: 3. Gauss’s Law – The total electric flux through any closed surface is proportional to the total electric charge inside the surface. Point Charge Inside a Spherical Surface: – The flux is independent of the radius R of the sphere.

What is the equipotential surface of electric field?

The Equipotential surface is the imaginary surface in an electric field on which the value of electric potential is same at all the points of it. The shape of equipotential surface are different in different electric field. , B.SC – Physics Hons. Dayalbagh Educational Institute Why does the magnetic flux density become zero on a closed surface?

What is the relationship between electric charge and electric flux?

Electric Flux and Enclosed Charge: -There is a connection between sign of net charge enclosed by a closed surface and the direction of electric flux through surface (inward for -q, outward for +q). – There is a connection between magnitude of net enclosed charge and strength of net “flow” of E.
