Additional information
Surface charge density is a concept in electromagnetism that quantifies the amount of electric charge distributed over a given area on the surface of an object or a conductor. It measures the charge per unit area and is used to describe the charge distribution on charged surfaces.
Mathematically, surface charge density (σ) is defined as the ratio of the total electric charge (Q) on the surface to the total area (A) of the surface:
Surface charge density (σ) = Q / A
The standard unit for surface charge density in the International System of Units (SI) is coulombs per square meter (C/m2). However, in some cases, microcoulombs per square centimeter (µC/cm2) or other units may be used for convenience.
