Electric flux is a scalar quantity, because it's the dot product of two vector quantities, electric field and the perpendicular differential area.
This is written in terms of differentials as:
dΦE = E � dA,
where dΦE is the differential electric flux, E is the electric field, and dA is the perpendicular differential area. Bolded quantities are vectors.
However flux-density is a vector quantity and electric flux density is related to electric field by a constant called the permittivity.
Electric flux density is a vector quantity, typically denoted by the symbol D. It is defined as the electric flux per unit area and points in the direction of the electric field.
Electric flux is a scalar quantity, as it represents the amount of electric field passing through a given area. It does not have a direction associated with it, unlike vector quantities.
No, electric flux is a scalar quantity. It represents the total number of electric field lines passing through a given surface.
Yes, electric flux can have a negative value if the electric field and the area vector have opposite directions.
The quantity symbol for electric flux density is D.
The electric flux through a surface is a measure of the total electric field passing through that surface. It is calculated by taking the dot product of the electric field and the surface area vector. The unit of electric flux is Newtons per Coulomb (N/C).
