Area charge density refers to how much charge is distributed over a given area. It quantifies how concentrated or spread out charges are on a surface.
Linear charge density (λ): Linear charge density refers to how much charge is distributed along a line per unit length.
Volume charge density (ρ): Volume charge density describes how much charge is distributed within three-dimensional space per unit volume.
Charge distribution: Charge distribution refers to how charges are arranged or spread out within a given region or object.
