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.
Why it is not possible to measure the drift speed for electron by timing their travel along the conductor?
It's difficult to accurately measure drift speed by timing electrons because individual electrons move randomly at high speeds, making it hard to track their motion. Also, electrons in a conductor have different velocities and directions, making it challenging to calculate an average drift speed. The collective drift speed of electrons in a current can be measured indirectly by observing the overall current flow in the conductor.
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.
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 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.
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.
Is an electric current a movement of electrons at near the speed of light?
No, electric current is the flow of electrons through a conductor, but the individual electrons do not move at near the speed of light. Instead, the speed of electron movement in a conductor is typically much slower.
Electrons move at the speed of light through conductors?
No. Three types of speed must be distinguished here: 1. The random movement of electrons is pretty fast, but still only a fraction of the speed of light. They will have this movement, whether there is a current or not. 2. The drift velocity is the average velocity of electrons when there is a current. This velocity is typically a fraction of a millimeter per second. 3. The velocity of the electric signal itself is typically about 2/3 the speed of light in a vacuum (that is, about 200,000 km/sec). What happens here is that energy is transferred from one electron to another. Imagine one electron bumping into another and pushing it forwards.
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 do you calculate set and drift?
Set and drift are typically calculated in the context of navigation and maritime operations. Set refers to the direction of the current's flow, while drift quantifies the distance moved by a vessel due to that current over a specific time. To calculate them, you can use vector analysis: determine the vessel's course and speed, then measure the current's speed and direction. By combining these vectors, you can find the resultant path of the vessel, which gives you the set and drift values.
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.
