In electricity, current refers to electric current, which is the flow of electric charge. Lightning is an example of an electric current, as is the solar wind, the source of the polar aurora. Probably the most familiar form of electric current is the flow of conduction electrons in a metallic wire. This is how the electric company delivers electricity.
The rate of flow of electricity. The unit of the ampere (A) defined as 1 ampere = 1 coulomb per second.
The flow of electricity in a circuit. The term current refers to the quantity, volume or intensity (1) of electrical flow, as opposed to voltage, which refers to the force or "pressure" causing the current flow.
A body of air, water, etc. that moves in a definite direction.
occurring in or belonging to the present time; "current events"; "the current topic"; "current negotiations"; "current psychoanalytic theories"; "the ship's current position"

It is the flow of electrons in metals or wires; or it could be the flow of electrons (in one direction) & ions (in the opposite direction) in more complex media.
The amount of current (in a wire) is the number of electrons passing a given point (measured in coulombs of charge) in one second. Then 1 coulomb/sec. = 1 ampere of current.
Since the amount of charge on one electron is 1.6e-19 coulombs; one ampere is equal to 6.25e18 electrons passing the measurement point in 1 second. That's 6.25 x 1 billion x 1 billion, a huge number.

current in physics is the amount of charge that passes through a wire in a time interval
I = dQ/dt

because of the category you filed this in, i suppose you mean "electrical current." it is a measure of electron motility or flow rate in a wire or other electrical power transmitter or carrier.
