Define electric flux and its si unit?
An electric field's property is electric flux.
It can be compared to the number of forces that cross a certain area.
Electric field lines are commonly thought to begin with positive charges and conclude with negative charges.
Negative field lines are those that are directed into a closed surface, whereas positive field lines are those that are directed out of a closed surface.
If no net charge exists within a closed surface, every field line directed into the surface passes through the interior and is usually directed outward elsewhere on the surface.
The negative flux just equals the positive flux in magnitude, resulting in a net or total electric flow of zero.
When a net charge is imprisoned inside a closed surface, the total flux through the surface is proportional to the enclosed charge, positive if the charge is positive and negative if the charge is negative.
SI unit of electric flux (N m 2 C -1 )
Dimensional formula of electric flux
We now know that (N m 2 C -1 ) is the SI unit for electric flux.
M = MASS.
L = LENGTH.
T = TIME.
I = CURRENT
[M L 3 T −3 A −1 ] is the dimension of electric flux.
