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 the … Ver mais 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 … Ver mais Current density is important to the design of electrical and electronic systems. Circuit performance depends strongly upon the designed … Ver mais 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 … Ver mais • Hall effect • Quantum Hall effect • Superconductivity • Electron mobility Ver mais 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.
