Definition

scalar quantity representing the areal distribution of electric charge,

σ = σ (r) = \frac{d Q}{d A}

where $d Q$ is a quasi-infinitesimal (see IEC 60050-121,locality:item="121-11-06") electric charge (electric charge) contained in a quasi-infinitesimal 2D domain located at position $r$ , and $d A$ is a quasi-infinitesimal area (ISO 80000-3: Space and time) of this domain
