That depends upon the type of metal you are using, but something along the lines of 1x10^-5 m/s is alright

How do two conductors have different currents even though the electrons in each conductor are travelling at the same speed?
There is a larger volume of electrons moving in the one that has the most current.
Describe the motion of a ball in a typical sport?
Since a ball is a sphere the motion it makes is rolling. The rolling happens on the ground and in the air.
How does the movement of electrons between two objects cause buildup of electric charges?
Electrons are negatively charged, they don't have to move to be that. If they do move in an otherwise electrically neutral material, they leave behind an imbalance in charge that is positive. The question is poorly worded, possibly because of confusion, but in reality, nothing creates any charge, ever - charge is a fact of nature, it is always present and does not change. All that may change is the balance of positive and negative charges in any one spot.
How fast is the gulf stream?
current velocity is fastest near the surface, with the maximum speed typically about 2.5 m/s (approx. 4.9 knots).
What does power divided by speed equal?
Ohm so correctly said: Voltage divided by current equals resistance. Voltage divided by current will tell you the value of a circuit's resistance. But resistance is not affected by either voltage or current. It is determined by the length, cross-sectional area, and resistivity (type of conducting material) of the conductor. Resistivity is, in turn, affected by temperature. So voltage divided by current tells you what the resistance happens to be - changes in voltage or current do not affect resistance.
How fast do electric currents move?
Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec. Note that the drift speed of the electrons is only a fraction of a millimeter per second, and the random speed of electrons is faster, but still much slower than the speed of the CURRENT.Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec.

Drift speed in a conductor that carries current?
The Drift Speed is less than the average speed of the electron between two collisions. Electrons move relatively slowly along a wire but very quickly between collisions. The electric field (EMF) that causes the motion moves at the speed of light.
Does the current and light travels at same speed?
Actually it is an interesting fact to be known thoroughly Current through metal is due to the drift flow of electrons. Actually that drift velocity is just 0.1 mm /s Very very slow. But how does the bulb glow so immediately as switch on the circuit? Here though electrons get drifted at such a low speed, that disturbance alone has been passed on from one region to the other at high speed. Hence we sense as if the current has passed at the speed of light. But acutally we cannot say that current flows at such a high speed.
What are electrons moving in a current is called?
The speed at which electrons flow along the wire is called the current. The measurement for current is amps.
Do electrons in a DC circuit travel at the speed of light?
The electrons themselves do not move at the speed of light. Electrons in a DC circuit move because of the application of an electric field. Like molecules in a gas, the charge carriers, electrons, undergo a Brownian-like motion through the conductor. The average drift velocity can be calculated by I=nAvQ, where I is current, n is the number of charged particles, A is the cross section area of the conductor, v is drift velocity, and Q is the charge on each particle.
What is the average speed of the world's most powerful current in centimetres per second?
This will depend not only upon the strength of the current (in Amperes), but also on the wire's cross-section. In any case, in a typical current, the electrons have an average speed of a tiny fraction of a milliter per second.
What is the average speed of electricity?
There are three different speeds here.The average speed of electrons - whether there is a current or not - is a significant fraction of the speed of light. That speed depends on the temperature. (The average VELOCITY of course is zero if there is no current, since as many electrons will go in one direction as in another.) The drift velocity (the average velocity) of the electrons is a small fraction of a millimeter per second. The exact value depends on the current, the cross section, and the material. The speed at which a signal can propagate in copper is about 2/3 of the speed of light in a vacuum - so, about 200,000 km/second. It is this speed that makes your light react quickly when you activate a switch.
Is an electric current a movement of electrons at near the speed of light?
No. The current travels near the speed of light; the individual electrons don't. Rather, energy is transferred from one electron to the next.
Does electricity travel closer to the speed of sound or light?
Electrons, that make up an Electric Current move at the Speed of Light.Further CommentAlthough electrons move rapidly, their movement is quite chaotic. But the actual drift of electrons along a conductor -i.e. current- is V-E-R-Y slow. So slow, in fact, that an individual electron, flowing through a flashlight bulb's filament, is unlikely to travel the length of that filament during the lifetime of its battery,
How does electricity flow through conductors?
Electric current - a movement or flow of electrically charged particles, typically measured in amperes.In a conductor, current flow is via a drift of free electrons in the metal. the actual drift rate may be slow, the electric field that drives them itself propagates at close to the speed of light, enabling electrical signals to pass rapidly along wires.See related link belowElectricity can flow through a conductor because it allows the electrons to move freely through the object. With an insulator, electrons cannot move.
Does electrons rely flows during current cundetion in matal?
The electrons do move - but mostly, the energy is transferred from one electron to another. The average speed of individual electrons is typically only a fraction of a millimeter per second; the current, on the other hand, has a speed of about 2/3 the speed of light in a vacuum. The current can be understood as a wave - the transfer of energy from one group of electrons to the next.
How does electrical current flow?
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!
