In a conducting wire, an electrical current will flow at about 2/3 the speed of light in a vacuum, or 200,000 km/sec. Note that the speed of the individual electrons is quite a bit less, and the average speed of the electrons is less than a millimeter per second. It is the CURRENT that advances at 2/3 the speed of light, not the electrons.
AnswerThe free electrons in a metal conductor move in random directions at a very high speed -a little less than the speed of light. This is the case whether or not a potential difference (or an electric field) is applied across the ends of that conductor.
However, when a potential difference is applied, these randomly-moving electrons are slightly biased towards the positive end of the conductor. So if a randomly moving but unbiased electron would normally end up at, say, point A, within the conductor then, under an electric field, it would end up at point B instead -where point B is typically less than the diameter of an atom away from point A. So individual electrons move along a conductor at speeds in the order of millimetres per hour.
As current is defined as a drift of electric charge (free electrons, in the case of metal conductors), this means that the velocity of this drift and, therefore, an electric current is very, v-e-r-y, slow! However, the effect of that current is felt immediately along the whole length of that conductor in much the same way that a number of railway wagons respond, practically instantaneously, to a small movement of just one of those wagons.
Electric current is so slow that, in practical terms, it's unlikely that an individual electron will complete its journey through the filament of a flashlight within the lifetime of its battery!
=== === electric current flows due to the flow of electrons from lower potential to higher potential. It is due to the drift velocity of electrons.
it is the flow of electrons
Electrical conductors.
A load increases the flow of electrical current in a series circuit. No load, no flow.
current is the flow of charge.
The flow of an electrical current be -- Coulombs per Second or Ampere hours per hour.
Electrons flow because of electrical attraction and repulsion.
A flow of electrical charges running through a medium is known as an electrical current.
In automotive, electrical circuits current is considered to flow from the battery. Most cars will have a 12-volt battery which will provide the electrical circuits current.
A flow of electrons in an electrical circuit is called a current, which is the name given to the amount of electrical charge flowing in a certain period of time.Any total quantity of electrical charge is measured in coulombs.Any flow of electrical current is measured in amps.1 amp is equal to a flow of 1 coulomb of electrical charge in one second of time.
The flow of electrons is called an electrical current.
current electricity is where electrons flow through a conductor.static electricity electrons do not flow
The flow of electricity is called electrical current.
Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.
