1. The continuous forward movement of a body of water; such as, a river: Fred realized that he couldn't paddle against the current in the stream for much longer; so, he tried to move over to the side.
2. A flow of electricity: The lights flickered a lot last night because of the unsteady current during the storm.
3. A common movement or tendency in society: A current of popular belief often decides a presidential election.

Descriptive of the present time or being in progress now: Tim's current resume is up-to-date, so now he is looking for a job.

1. The time rate of flow of an electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit of time measured in amperes.
2. Charged particles, most often electrons, moving through a conductor or transmitter; such as, copper and aluminum.
3. A flow of charged particles; such as, electrons or protons, accompanied by the field which they generate.
4. Movement of electric charge carriers.

In a wire, electric current is a flow of electrons that have been dislodged from atoms and is a measure of the quantity of electrical charge passing any point of the wire per unit of time.

Alternating Current current

The world's largest ocean current which circles the globe and feeds cold water into the Atlantic, Pacific, and Indian Oceans.

The vertical movement of air currents resulting from temperature variations: Mr. Air explained the facts concerning atmospheric convection currents and that they arose from the changing differences in heat and cold in the atmosphere.

Direct Current current.

The current per unit of a cross-sectional area of a conductor.

1. An instrument that is used for measuring the magnitude of electric current flow.
2. A device which is used to measure the magnitude of an electric current of several amperes or more.

An ammeter is usually combined with a voltmeter and an ohmmeter in a multipurpose tool.

The current that flows in a photodetector when there is no optical radiation incident on the detector and operating voltages are applied.

1. A movement of charged particles in the atmosphere giving rise to electric and magnetic fields; such as, those in the ionosphere that transmit radio signals.
2. Motions of charged particles; for example, in the ionosphere, that are giving rise to electric and magnetic fields.

1. A voltmeter consisting of a direct-current milliammeter calibrated in volts and connected to an amplifier-rectifier circuit.
2. A device that measures voltage in amplifier-rectifier circuits.

1. An electronic instrument which adjusts the speed of a DC (direct current) motor when it is driven by an AC (alternating current) power line.
2. A control circuit used to change or to vary the speed of a direct-current (DC) motor operated from an alternating-current (AC) power line.

Silicon controlled rectifiers or power transistors rectify or correct the voltage and vary the field current of the motor.

Any of three types of electric current, which, when introduced into biologic tissue, is capable of producing specific physiologic changes.

The three types are direct monophasic, alternating biphasic, and pulsed polyphasic electric current.

A current induced in a nerve sheath without the creation of a new current by an action potential or a momentary change in electrical potential on the surface of a neuron or muscle cell.

Electricity that flows from a conductor to the ground or to another conductor because of something being wrong with the connections: Since there was a fault-current in the electrical system in Adam's old house, he often blew a fuse when he tried to turn on his lights.

1. An essentially steady, direct current produced by galvanic action or chemical activity.
2. A steady direct current; especially, one that is produced chemically.

A wind, ocean current, or other such movement in which the horizontal force is exactly balanced by the apparent force exerted on a moving object by the rotation of the Earth: When studying oceanography, Jill learned that the Gulf Stream, the Kuroshio Current, the Antarctic Circumpolar Current, and the Agulhas Current were all examples of geostrophic currents.

1. A current caused by a flow of positively charged ions.
2. The electric current resulting from the motion of ions.

1. A current produced in an ionized gas by an electric field.
2. A positive-ion current produced by collisions between electrons and residual gas molecules in an electron tube.

In particle physics, a weak interaction in which no electric charge is exchanged between the colliding particles.

A density current in the ocean whose flow is caused by its relatively higher salinity, and therefore its greater density, in comparison to the surrounding water.

1. In an electron tube, the valence of the anode current which does not further increase with an increase in anode voltage.

The term anode is a general term for the electrode, terminal, or element through which current enters a conductor; so called from the path the electrical current was thought to take.

2. A situation in which the anode current of an electron tube can not be further increased by increasing the anode voltage.

The electrons are then being drawn to the anode at the same rate as they are emitted from the cathode.

1. The replacement of elements of one circuit pair by their dual elements in another circuit, according to the duality principle.
2. A pair of circuits in which the elements of one circuit are replaced by their dual elements in the other circuit according to the duality principle; for example, currents are replaced by voltages, capacitances by resistances.
