## 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. Physics
a. a flow of electric charge through a conductor
b. the rate of flow of this charge. It is measured in amperes

## 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 = Δqt. The unit of current is the ampere. Current is measured by means of ammeters.

## current

(electricity)

## 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

(1) The flow of electrons through a circuit. Measured in "amperes." See amp and voltage.

The third day, in the morning, the wind having abated overnight, the sea was calm, and I ventured: but I am a warning to all rash and ignorant pilots; for no sooner was I come to the point, when I was not even my boat's length from the shore, but I found myself in a great depth of water, and a current like the sluice of a mill; it carried my boat along with it with such violence that all I could do could not keep her so much as on the edge of it; but I found it hurried me farther and farther out from the eddy, which was on my left hand.

Next, for about a half an hour, I whoops now and then; at last I hears the answer a long ways off, and tries to follow it, but I couldn't do it, and directly I judged I'd got into a nest of towheads, for I had little dim glimpses of them on both sides of me -- sometimes just a narrow channel between, and some that I couldn't see I knowed was there because I'd hear the wash of the current against the old dead brush and trash that hung over the banks.

In the awful stench of these frightful charnel isles haggard maniacs screamed and gibbered and fought among the torn remnants of their grisly feasts; while on those which contained but clean-picked bones they battled with one another, the weaker furnishing sustenance for the stronger; or with clawlike hands clutched at the bloated bodies that drifted down with the current.
