In electromagnetism, charge density is the amount of electric charge per unit length, surface area, or volume. Volume charge density (symbolized by the Greek letter ρ) is the quantity of charge per unit volume, measured in the SI system in coulombs per cubic meter (C⋅m −3), at any point in a volume. The charge density refers to the amount of charge per unit area on the plates, while the permittivity is a measure of how easily electric fields can penetrate a material. By adjusting these factors, it is possible to manipulate the electric field strength between the plates.
