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 nearby dipoles tending to line them up, the net accumulation of charge from the orientation of the dipoles is the … See more 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 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 See more In special relativity, the length of a segment of wire depends on velocity of observer because of length contraction, so charge density will … See more The charge density appears in the continuity equation for electric current, and also in Maxwell's Equations. It is the principal source term of the electromagnetic field; when the charge distribution moves, this corresponds to a current density. … See more For a single point charge q at position r0 inside a region of 3d space R, like an electron, the volume charge density can be expressed by the Dirac delta function: As always, the … See more In quantum mechanics, charge density ρq is related to wavefunction ψ(r) by the equation When the … See more • Continuity equation relating charge density and current density • Ionic potential • Charge density wave See more WebElectric Field: Sphere of Uniform Charge.
