the current density
1Current density — This page is about the electric current density in electromagnetism. For the probability current density in quantum mechanics, see Probability current. Current density is a measure of the density of flow of a conserved charge. Usually the charge… …
2Current density imaging — (CDI) is an extension of magnetic resonance imaging (MRI), developed at the University of Toronto. It employs two techniques for spatially mapping electrical current pathways through tissue: LF CDI, low frequency CDI, the original implementation… …
3current density — n. the amount of electric current passing through a cross sectional area (perpendicular to the direction of current) of a conductor in a given unit of time: commonly expressed in amperes per square centimeter or amperes per square inch …
4current density — noun : the current per unit area of cross section perpendicular to flow in a region through which an electric current is flowing …
5current density — Elect. the amount of current flowing through a given cross sectional area in a given time interval: usually measured in amperes per square centimeter. * * * …
6current density — cur′rent den sity n. elm the amount of current flowing through a given cross sectional area in a given time interval: usu. measured in amperes per square centimeter …
7current density — /ˈkʌrənt dɛnsəti/ (say kuruhnt densuhtee) noun the rate of flow in amperes per unit of cross sectional area at a given place in a conductor, or more generally, current per unit area …
8Current filament — A current filament is an inhomogeneity in the current density distribution lateral to the of the current flow (that is, orthogonal to the current density vector). It is common in the devices showing current type negative differential conductivity …
9Current sources and sinks — are analysis formalisms which distinguish points, areas, or volumes through which current enters or exits a system. While current sources or sinks are abstract elements used for analysis, generally they have physical counterparts in real world… …
10Current crowding — (also current crowding effect, or CCE) is a nonhomogenous distribution of current density through a conductor or semiconductor, especially at the vicinity of the contacts and over the PN junctions. Current crowding is one of the limiting factors… …
