Question

what do you mean by electric flux?

Answer 1

electric feild lines passing perpendicularly to a given area

Answer 2

sure??? coz i m going to write this deifinition in exam -_-

Answer 3

Each electrically charged particle acts on another even though there is no visible connection between them. The intensity with which this action occurs is pictured by the flux surrounding that charge. If you imagine the charge as a water tap,it is like the amount (not force) of water flowing out of it. As another answerer has already said, it is a surface integral of electric field strength emerging perpendicular to the surface over which you want to know the flux.

Answer 4

hey hey c'mon i not good in cramming :P give me an easy difinition dat i can write in xam lol :P

Answer 5

@apoorvk @Vincent-Lyon.Fr

Answer 6

flux - no. of field line crossing a particular surface, is flux through it.

be it magnetic/electric/any bla-bla flux!

Answer 7

Under an electric field, magnitude and direction of electric intensity is different in every point.If the electric intensity can be defined through a closed line (direction of electric intensity will be along the tangent of any point of that line)this is called electric lines of force.
Electric lines of forces passing through an closed electric surface perpendicularly, is called electric flux.

Answer 8

i guess it should be like this
flux - no. of electric line held in a electric field crossing surface in a perpendicular manner is called flux

Answer 9

*feild lines

Answer 10

@apoorvk is my definition is correct?

Answer 11

@heena Electric lines of forces passing through an closed electric surface perpendicularly, is called electric flux.

Answer 12

Flux is 'amount' of field crossing a surface.

Answer 13

ok by mixing above difinition i m writing
no . of electric feild lines held in a electric field passing through an closed electric surface perpendicularly is called flux and its SI unit is Nm^2/C

Answer 14

Reference to number of field lines might satisfy your teacher, but is true only if flux is conservative.
In the case of electric field, this holds in a region of space where \(\rho =0\), not elsewhere.

Answer 15

Surface is not necessarily closed.

Answer 16

guys i m having exam dont confuse me -_- decide and tell me its closed or not :P

Answer 17

ok guys what is the relation between electric flux and intensity ? 2marks

Answer 18

Flux = S x (E cos θ)
Flux is product of surface area by component of field normal to the surface.

The surface here has a boundary, so it is not a closed surface.
