In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of … See more Assume that A (SI unit: m ) is a small surface centred at a given point M and orthogonal to the motion of the charges at M. If IA (SI unit: A) is the electric current flowing through A, then electric current density j at M is … See more Current density is important to the design of electrical and electronic systems. Circuit performance depends strongly upon the designed current level, and the current density then is determined by the dimensions of the conducting elements. For example, as See more Since charge is conserved, current density must satisfy a continuity equation. Here is a derivation from first principles. The net flow out of some volume V (which can have an … See more • Hall effect • Quantum Hall effect • Superconductivity • Electron mobility See more Free currents Charge carriers which are free to move constitute a free current density, which are given by expressions such as those in this section. Electric current is a coarse, average quantity that tells … See more In electrical wiring, the maximum current density (for a given temperature rating) can vary from 4 A⋅mm for a wire with no air circulation around it, to over 6 A⋅mm for a wire in free air.
