Despite referring to many different things the word current is often used by itself instead of the longer more formal electric current.
Electric a current.
Electric current is defined as the rate at which charge flows through a surface the cross section of a wire for example.
More specifically the electric current is the rate of charge flow past a given point in an electric circuit.
The electrical current is measured in ampere amp unit.
Using water pipe analogy we can visualize the electrical current as water current that flows in a pipe.
When two point of different electric potential are connected by a conductor charge flows so long as a potential difference exists.
Electric current is electric charge in motion.
If the two requirements of an electric circuit are met then charge will flow through the external circuit.
An electric current is said to exist when there is a net flow of electric charge through a region.
Electric charge is carried by charged particles so an electric current is a flow of charged particles.
The ampere ˈ æ m p ɪər æ m ˈ p ɪər or ˈ æ m p ɛər uk symbol.
The international system of units defines the ampere in terms of.
The charge can be negatively charged electrons or positive charge carriers including protons positive ions or holes.
It is said that there is a current a flow of charge.
It can take the form of a sudden discharge of static electricity such as a lightning bolt or a spark between your finger and a ground light switch.
Electric current in a wire where the charge carriers are electrons is a measure of the quantity of charge passing any point of the wire per unit of time.
The adjective electric is implied by the context of the situation being described.
Electrical current is the flow rate of electric charge in electric field usually in electrical circuit.

An electric current is the rate of flow of electric charge past a point or region.
A often shortened to amp is the base unit of electric current in the international system of units si.
In alternating current the motion of the electric charges is periodically reversed.
In direct current it is not.
Using the word current in this context is to simply use it to say that something is happening in the wires charge is moving.
