the movement of electrically charged particles, atoms, or ions, through solids, liquids, gases, or free space; the term is usually used of relatively smooth movements of electric charge through conductors, whether constant or variable. Sudden movements of charge are usually referred to by other terms, such as spark or lightning or discharge. In metallic conductors the electric current is usually due to movement of electrons through the metal. The current is measured as the rate of movement of charge per unit time, and is counted in units of amperes. As a formal definition, the direction of movement of electric current is considered as the same as the direction of movement of positive charge, or in a direction opposite to the movement of negative charge. Electric current may move constantly in a single direction, called direct current (abbreviated DC), or may move alternately in one direction and then the opposite direction, called alternating current (abbreviated AC).
current; electrical current. A flow of electric charges. The SI unit of electric current is the ampere.
A flow of electrons; electricity, amps.
A flow of electric charge.
The flow of electric charge. The preferred unit of measure is the ampere.
moving electrical charges
Flow of electricity through a conductor or transmitter.
electrical current: the flow or rate of flow of electrons or ions in a conductor or medium between two points having a difference in electrical potential.
The movement of electrons along a conductor.
(I) The rate at which charge flows through a surface perpendicular to the direction of flow.
A flow of electrons through a conductor, the size of the current is proportional to the rate of electron flow.
the flow of electronically charged particles through a conducting circuit due to the presence of a potential difference. The current at any point in a circuit is the amount of charge flowing per second; its SI unit is the ampere (coulomb per second).

The movement of electric charge carriers in a medium.
A flow of electrons through a wire or other electrical conductor. Electrons are negatively charged particles of matter.
The flow of electrons measured in amps.
Motion of electric charges. If we look at a conducting wire, it is the number of charges passing through a section of the wire each second. The electric current is measured in Ampère (A): 1 A = 1 C / 1 s
A flow of electrons in an electrical conductor. The strength or rate of movement of the electricity is measured in amperes.
The flow of electrons measures in Amperes or Amps.
Flow of electrons. Current is measured in amperes (A) and is represented by the letter I in formulas.
movement of electricity, measured in charges per second (just as river current is measured in liters per second)
The volume of electricity propelled by the voltage; a flow of electrons.
the continuous flow of electrons; often referred to as electricity.
A flow of electrically charged particles such as electrons with a conductor or a circuit. See Conduction, Electricity.
a continuous flow of electrons and/or ions, through a material with conducts electricity. A currents usually flows in a closed circuit, without beginning or end. In daily life currents are generally driven through wires by voltages, produced by batteries or generators. In space plasmas, some currents may be produced this way, but many are inherent to the way ions and electrons move through magnetic fields, e.g. their drifts.
Magnitude of the flow of electrons.
The rate at which electricity flows through an electrical conductor, usually measured in amperes (amps).
(also Current) A flow of electrically charged particles such as electrons within a conductor or a circuit. See Conduction.
Electric current is the flow of electric charge. The SI unit of electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second.
