charge density

This term is a technical specification used primarily in physics and electrical engineering to describe how electric charge is distributed across a space. It is a quantitative measure that allows scientists to calculate the resulting electric field and potential of a given object.

Depending on the geometry of the object, the term is used in three distinct contexts: linear charge density (charge per unit length), surface charge density (charge per unit area), and volume charge density (charge per unit volume). In professional discourse, the specific type of density is usually specified to avoid ambiguity.
