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.
Current flows in copper wire due to the movement of electrons. When a voltage is applied across the wire, the free electrons in the copper atoms gain energy and move in the direction of the electric field, creating an electric current. The high conductivity of copper allows for efficient flow of electrons through the wire.
Your 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!

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, a rubber tubing is an insulator and will not allow the flow of electric current like a conductor such as copper wire would. Therefore, if the copper wire is replaced by rubber tubing, the circuit will be broken and no current will flow.
What is the predominant carrier of electrical charge in a copper wire?
The predominant carrier of electrical charge in a copper wire is the free electrons within the copper atoms. These free electrons are able to move easily through the lattice structure of the copper, allowing for the flow of electric current.
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.
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.
How do you measure electrical current flow in a copper wire?
Electrical current flow in a copper wire is typically measured using an ammeter, which is connected in series with the wire. The ammeter measures the flow of electrons in the wire and displays the current in units of amperes (A). Make sure to set the ammeter to the appropriate range before taking the measurement.
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, a rubber tubing is an insulator and will not allow the flow of electric current like a conductor such as copper wire would. Therefore, if the copper wire is replaced by rubber tubing, the circuit will be broken and no current will flow.
Electric current in a copper wire is normally composed of what?
Electric current in a copper wire is composed of moving electrons. When a voltage is applied across the wire, the free electrons in the copper atoms move in response to the electric field, creating the flow of current.
If a certain voltage is applied to a copper wire and to a germanium wire of the same thickness and length how will the current in the two wires compare?
The current in the copper wire will be higher than the current in the germanium wire. This is because copper has lower resistance compared to germanium, allowing more current to flow for a given voltage. Germanium has higher resistance due to its crystal structure, which hinders current flow.
Is copper wire a condutor or insulator?
Copper wire is a conductor of electricity. Its high conductivity allows electric current to flow easily through it.
Why does more current flow through the bulb when the reed switch was replaced with copper wire?
When the reed switch is replaced with copper wire, the circuit becomes a short circuit with low resistance, allowing more current to flow through the bulb. The reed switch typically adds resistance to the circuit, limiting the amount of current that can flow. Removing it with copper wire eliminates this resistance, allowing more current to pass through.
Is a copper wire a insulator or conductor?
Copper wire is a conductor. Copper is commonly used in wiring because it easily allows the flow of electric current due to its high conductivity.
Does copper wire carry electric current?
Yes, copper wire is an excellent conductor of electric current due to its high electrical conductivity properties. When a voltage is applied across the wire, it allows the flow of electrons, resulting in the transmission of electric current through the wire.
How could Theresa cause an electric current to flow through one of the copper wires studyisland?
To cause an electric current to flow through one of the copper wires, Theresa would need to connect the wire to a power source, such as a battery or electrical outlet. By completing a circuit with the wire connecting the positive and negative terminals of the power source, electrons will flow through the wire, creating an electric current.
Will a copper or steel wire of the same thickness and length allow more electric current to pass through?
A copper wire will allow more electric current to pass through compared to a steel wire of the same thickness and length. This is because copper has lower resistance to the flow of electricity, resulting in better conductivity.
What material will let electricity to flow between a battery and a lightbolb?
A conductor like copper wire is the material that allows electricity to flow between a battery and a lightbulb. Conductors have free electrons that can move easily, enabling the flow of electric current.
Why is thick copper wire good for carrying a current?
Thick copper wire has lower resistance than thinner wire, which allows more current to flow with less energy loss due to heating. This makes thick copper wire more efficient for carrying high currents without overheating. Additionally, thick copper wire is less prone to voltage drops over long distances compared to thinner wire.
