A set of (potentially infinitesimal) charges. It is described by the charge density function, which is the amount of electric charge per unit length, surface or area. It is a scalar field.

In case of point charges, linear or surface charges, the function contains Dirac deltas, because they are singular charge distributions.

Point charge

For a point charge with charge in position , the charge density is:
