Under what condition can the electric flux linked with a surface be positive?
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.
Can electric flux be positive or negative?
Yes,
electric flux can be a negative number
. When electric lines emerge out of surface, the electric flux is positive and when those lines enter into a surface, the electric flux in negative.
What does it mean when flux is positive?
When the field vectors are going the same direction as the vectors normal to the surface
, the flux is positive. When the field vectors are going the opposite direction as the vectors normal to the surface, the flux is negative.
Under what condition the electric flux through a surface is maximum and when flux becomes minimum?
Electric flux through a surface is at *maximum
* when the electric field is perpendicular to the surface
. The whole point of flux is to measure the “total number of field lines” punching through a surface. If the electric field is lying *along* the surface, it isn’t going in or going out and the flux is zero.
How do you define electric flux linked with a surface?
Electric flux is the rate of flow of the electric field through a given area (see ). Electric flux is
proportional to the number of electric field lines going through a virtual surface
.
How do you find flux on a surface?
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 does electric flux depend on?
The numerical value of the electric flux depends on
the magnitudes of the electric field and the area
, as well as the relative orientation of the area with respect to the direction of the electric field.
When the electric flux linked with the surface will be positive theta will be?
Hi Jayesh, Positive flux means flux is
leaving the hose
; the hose is a source of flux. Negative flux is like water entering a sink; it is a sink of flux.
Is it possible to have zero electric flux for a surface in an electric field?
The electric flux
will be zero only if there is no charge enclosing that surface
. However if you place an uncharged sphere in a uniform electric filed, the sphere develops induced charges.
What is electric flux and its unit?
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 exactly is flux?
Flux is
the presence of a force field in a specified physical medium
, or the flow of energy through a surface. … Flux is depicted as “lines” in a plane that contains or intersects electric charge poles or magnetic poles.
Does flux have direction?
These fluxes are vectors at each point in space, and
have a definite magnitude and direction
. Also, one can take the divergence of any of these fluxes to determine the accumulation rate of the quantity in a control volume around a given point in space. For incompressible flow, the divergence of the volume flux is zero.
What do you mean by positive and negative magnetic flux?
Yes,
magnetic flux can be negative
. It just depends on where the field is going. Say there is a sheet and magnetic field is going through it from front to the back, we can call the flux there as positive and negative when it’s the other way round.
Which case has maximum flux?
Therefore, the electric flux of a surface is maximum
when the area vector is parallel to the direction of the electric field
.
At what angle is electric flux minimum?
The electric flux through the surface is minimum when the angle between
e and a
is. salonitomar2770 is waiting for your help.
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 of the vector field in the volume enclosed by the surface
.
