current flow in wire means electron move.when is conduct the electron move for the first positive cycle from 180 phase.then for negative half cycle it will move backward
it means electron stay its position on both cycle just external force is applied to make the device operate and electron which are in wire.

∙ 12y agoYour question should really be asking what is the charge(in this case, electrons) velocity through a copper conductor.
The velocity of the electron drift in a conductor is given by:
v = I/(n A e)
where:
- v = velocity (metres per second)
- I = current (amperes)
- n = number of electrons per cubic metre (8.5 x 1028 for copper)
- A = cross-sectional area of conductor (square metres)
- e =charge on a single electron (coulombs)
If you plug practical values into this equation, you will find that the velocity of electron drift will be a fraction of a millimetre per second -in other words, it is VERY slow! For example, it's unlikely that an individual electron will pass along the length of a flashlight filament before its battery becomes depleted!

How does the flow of current within the simple cell differ from that in a copper wire?
One terminal of a cell or battery is positive, while the other is negative. It is convenient to think of current as flowing from positive to negative. This is called conventional current. Current arrows in circuit diagrams always point in the conventional direction. However, you should be aware that this is the direction of flow for a positively-chargedparticle.In a copper wire, the charge carriers are electrons. Electrons are negatively-charged and therefore flow from negative to positive. This means that electron flow is opposite in direction to conventional current.
If a copper wire in a working electric circuit is replaced by a piece of rubber tubing will there be a current in the circuit?
no rubber stops the flow of electricity
What does copper wire do in an electrical circuit?
Because the metal Copper is a very good conductor - of both electricity and heat - copper wire can be used to carry an electric current in an electric circuit. The electric current consists of a flow of electrons.
Will a copper wire not carrying a current be attracted to a magnet?
No, a copper wire that is not carrying a current will not be attracted to a magnet. Copper is not a magnetic material, so it does not interact with magnetic fields in the same way that magnetic materials like iron or nickel do.
What refers to electric current when electrons always flow in the same direction in the wire?
When electrons always flow in the same direction in the wire it is known a DC (direct current).
How do you measure electrical current flow in a copper wire?
Electrical current flow in a copper wire is measured with an ammeter. It is either clamped onto the wire or attached at one end to monitor the amount of current moving through the wire.
Why does more current flow through the bulb when the reed switch was replaced with copper wire?
Copper wire has apparently lower resistance than the reed switch. The lower electric resistance, the higher electric current.
If 5.0 Coulombs of electrons flow past the middle of a copper wire in 0.10 seconds then what is the electric current in that wire?
The current is 50 Amperes, 5/.1=50Coul/sec.
Electric current in a copper wire is normally composed of what?
Electron current in a copper wire is normally composed of electrons.

What happens to copper wire because of the moving magnet?
The copper wire carries an electric current.
What is heavy copper wire used for?
Heavy copper wire is used for heavy current loads.
Why is copper commonly use to make electric wires?
Copper is used to make electrical wire because it is ductile and is very conductive. The ease with which copper can be worked and drawn ("pulled" or "stretched") into wire (because of its ductility) makes it a great mechanical choice for wire. And copper is highly conductive, that is, it has a low resistance to electric current flow. These two properties make copper an excellent choice to make electrical wire.
How does a current flow through a wire?
according to kcl the current flows through a wire
Moving a wire through a magnetic field does not create a current flow in a wire?
Not true - Moving a wire through a magnetic field doescreate a current flow in a wire.false
