Area charge density refers to the amount of electric charge per unit area. It is a measure of how much charge is distributed over a given surface.
Volume charge density (ρ): This term refers to the amount of electric charge per unit volume.
Linear charge density (λ): This term refers to the amount of electric charge per unit length along a line or wire.
Electric flux (Φ): This term represents the flow of an electric field through a given surface.
