current
1. a mass of air, body of water, etc., that has a steady flow in a particular direction
2. the rate of flow of such a mass
3. Physicsa. a flow of electric charge through a conductor
b. the rate of flow of this charge. It is measured in amperes

current
(electronics)The quantity of
charge per unit time, measured
in Amperes (Amps, A). By historical convention, the sign of
current is positive for currents flowing from positive to
negative
potential, but experience indicates that electrons
are negatively charged and flow in the opposite direction.

Current
(i), a scalar quantity characterizing the time rate of flow of electric charge. It is equal to the ratio of the charge Δq transported through the cross section of a conductor in the time Δt to the time: i = Δq/Δt. The unit of current is the ampere. Current is measured by means of ammeters.
