general relativity, the four-current (technically the four-current density) is the four-dimensional analogue of the current density, with units of charge...

An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net...

Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to...

In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability. Specifically...

Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through...

In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field...

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...

Look up current or Current in Wiktionary, the free dictionary. Currents, Current or The Current may refer to: Current (fluid), the flow of a liquid or...

Displacement current density has the same units as electric current density, and it is a source of the magnetic field just as actual current is. However...

quantum mechanics, the four-probability current or probability four-current is analogous to the electromagnetic four-current: J = ( ρ c , j ) {\displaystyle...
