ELECTRIC FLUX AND GAUSS"S LAW

 The word “flux” comes from the latin word meaning “to flow”
 For a vector field flux is the number of lines passing through a surface

Mathematically it is the product of the surface area  “A” and the component of the electric field “E” perpendicular to the surface
ΦE = EA Nm2 /C
If  area “A” is not exactly perpendicular to the electric field E
ΦE = EAcosf
Flux will be maximum when surface area is perpendicular to the electric field

ΦE = EA
Gauss's Law
The total electric flux through any closed surface is proportional to the total electric charge inside the surface
