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.
When electric flux is maximum or minimum?
Electric flux is zero if Electric field is parrallel to a surface and is maximum if it is perpendicular to a surface.
Under which of the following conditions is electric flux most minimum?
if the enclosed charge in the gausian surface is maximum then the flux through the surface is also maximum. & if the enclosed charge is minimum then the flux is also minimum. since flux is directly proportional to the enclosed charge.
Under what conditions can the electric flux?
If the magnitude of the electric field is known everywhere on the surface. If the total charge inside the surface is specified. If the total charge outside the surface is specified. Only if the location of each point charge inside the surface is specified.
Can you have negative flux?
The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. If a net charge is contained inside a closed surface, the total flux through the surface is proportional to the enclosed charge, positive if it is positive, negative if it is negative.
At what angle electric flux is minimum?
The electric flux through the surface is minimum when the angle between e and a is. salonitomar2770 is waiting for your help.
How is electric flux calculated?
The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field.
What is 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.
Is the flux through a closed surface always zero?
The flux of a vector field through a closed surface is always zero if there is no source or sink of the vector field in the volume enclosed by the surface. … The flux of a electric field through a closed surface is always zero if there is no net charge in the volume enclosed by the surface.
Do charges at rest produces electric field?
Charge at rest only produces electric field. Moving charge produces both electric field and magnetic field.
What is the net electric flux through closed surface?
The net electric flux is zero through any closed surface surrounding a zero net charge. Therefore, if we know the net flux across a closed surface, then we know the net charge enclosed.
