Sigma charge density
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 ), at any point in a volume. Surface charge … See more In dielectric materials, the total charge of an object can be separated into "free" and "bound" charges. Bound charges set up electric dipoles in response to an applied electric field E, and polarize other … See more For the special case of a homogeneous charge density ρ0, independent of position i.e. constant throughout the region of the material, the equation simplifies to: Proof Start with the definition of a continuous volume charge … See more In quantum mechanics, charge density ρq is related to wavefunction ψ(r) by the equation When the … See more The charge density appears in the continuity equation for electric current, and also in Maxwell's Equations.
