What is the orientation of the surface in electric field to get maximum flux through it?

The electric flux of a surface is maximum when the area vector is parallel to the direction of the electric field. The electric flux is the total number of lines of force passing through a surface. Electric flux is proportional to the number of electric field lines going through a virtual surface.

At what angle is flux zero and maximum?

Now if E is perpendicular to the surface then two vector will be parallel so angle between them will be zero and cos 0 =1 so the flux will be maximum.

What is the electric flux of a uniform electric field through a flat surface a?

zero
The net flux of a uniform electric field through a closed surface is zero.

What happens to the electric flux if the electric field is parallel to the surface?

If the surface is parallel to the field (right panel), then no field lines cross that surface, and the flux through that surface is zero. If the surface is rotated with respect to the electric field, as in the middle panel, then the flux through the surface is between zero and the maximal value.

What is the orientation of a surface?

For an orientable surface, a consistent choice of “clockwise” (as opposed to counter-clockwise) is called an orientation, and the surface is called oriented. For surfaces embedded in Euclidean space, an orientation is specified by the choice of a continuously varying surface normal n at every point.

How is the electric field oriented?

Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.

When electric flux is maximum and minimum?

If the planar surface is perpendicular to the electric field vector, the maximum flux would be obtained. b. If the planar surface were parallel to the electric field vector, the minimum flux would be obtained.

How do you find the maximum value of flux?

The formula for Maximum flux = V1= 4.44F∅N1 or V2=4.44F∅N2.

Can an electric field be uniform?

A field in which the value of the field strength is the same at all points. For example, a uniform electric field exists between two parallel charged plates.

Is electric field uniform in equipotential surface?

The electric field is always perpendicular to an equipotential surface. Two equipotential surfaces can never intersect. For a point charge, the equipotential surfaces are concentric spherical shells.

Does electric flux depend on shape?

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.

Is it possible to have zero electric flux for a surface in an electric field?

No, it is usually not zero. It is zero only if there is no electric charge enclosed in the closed surface. In simple math: Electric flux of the closed surface = Charge / permittivity.

How to find the electric flux of a uniform electric field?

Now that we have defined the area vector of a surface, we can define the electric flux of a uniform electric field through a flat area as the scalar product of the electric field and the area vector, as defined in Products of Vectors: Φ = E → · A → ( uniform E →, flat surface). Φ = E → · A → ( uniform E →, flat surface).

What is the electric flux through the top face of a surface?

E → is in the opposite direction to the normal to the surface. 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.

What happens to flux when the area is rotated?

The larger the area, the more field lines go through it and, hence, the greater the flux; similarly, the stronger the electric field is (represented by a greater density of lines), the greater the flux. On the other hand, if the area rotated so that the plane is aligned with the field lines, none will pass through and there will be no flux.

Is the net electric flux crossing an open surface always zero?

The net electric flux crossing an open surface is never zero. True or false? 5 . Two concentric spherical surfaces enclose a point charge q. The radius of the outer sphere is twice that of the inner one. Compare the electric fluxes crossing the two surfaces.
