firstly you need a battery or a cell to produce a p.d or to produce current (flow of electrons). the opp charges will always attract each other. therefore, the electrons travel through the wire from the -ve terminal of the battery to the +ve.

Protons do not attract electrons through a wire directly. In a wire, electrons flow due to an electric field created by a potential difference (voltage). When a voltage is applied across a wire, electrons move towards the positive terminal due to the attraction of the positive charges in that terminal.

Which of these is a metal wire that allows electrons to flow through it?
Copper wire is a common metal wire that allows electrons to flow through it easily due to its high electrical conductivity.
Why do electrons make up the flow of charge in a metal wire rather than protons?
Protons are located in the nucleus of the atom and under normal conditions are not free to move or flow. Electrons in the outermost shells of conducting metals like copper are weakly held and are free to flow. However, it's important to understand that electron flow and charge flow are not the same thing. It is the flow of an electric field through the wire that creates the effect we understand as electricity, not the actual movement of electrons, which is relatively slow.
What are ideas to make a homemade atom?
Use different sized beads for the protons and neutrons, and the electrons, and steel wire for the different orbitals.
Do magnets repel or attract copper wire?
Magnets attract copper wire as long as the wire is not magnetized. However, if the copper wire becomes magnetized, it can repel or attract other magnets depending on its polarity.
Atomic explanation as to why a piece of constantan wire with a large diameter has a smaller resistance than a piece of constantan wire with a small diameter?
A larger diameter constantan wire has more space for electrons to move through, reducing the chances of collisions with the atoms in the wire. This results in lower resistance because there are fewer obstacles for the electrons to overcome as they flow through the wire. Conversely, a smaller diameter wire has less space, leading to more collisions and higher resistance.
How do protons and electrons affect each other?
Protons and electrons attract each other due to opposite charges - protons are positively charged while electrons are negatively charged. This electrostatic force of attraction is what keeps electrons orbiting around the nucleus of an atom. The number of protons in an atom determines its atomic number and therefore its identity.
What is it called when electrons flow through a wire?
When electrons flow through a conductor such as a wire, it is called, "Electricity".
What is the number of electrons flowing through the wire?
The number of electrons flowing through a wire depends on the current passing through it. One ampere of current corresponds to approximately 6.24 x 10^18 electrons flowing through the wire per second.
What does a turbine spin around to make electrons flow in a wire?
Not around... moving THROUGH a magnetic field forces electrons to flow through a wire.
Which of these is a metal wire that allows electrons to flow through it?
Copper wire is a common metal wire that allows electrons to flow through it easily due to its high electrical conductivity.
What is generated around a wire as electrons flow through the wire?
An electromagnetic field is generated around a wire as electrons flow through it. This field has both electric and magnetic components and is responsible for the transmission of energy along the wire.
How current passes through wire?
though electrons
How does current electricity?
First you need to understand charge, voltage and current.Atoms are made of electrons, neutrons and protons. Electrons have a kind of charge called negative charge and protons have a positive charge. Neutrons have both negative and positive charges, so they cancel out and are not very important to electricity. Like charges repel each other, while opposite charges attract each other. This is what causes electricity.Sometimes atoms will have more electrons than protons or vice versa. When there are many atoms of something have too few or too many electrons then it gains a net charge depending on if there are more electrons or more protons. If there are more electrons then it has a negative charge, if it has more protons it has a positive charge.Voltage is the difference between two charges. On a 9-volt battery, the difference between charge of the positive terminal and the negative terminal will be nine times as much as the difference of charge on the terminals of a 1-volt battery.Now since opposite charges attract, the electrons in the negative terminal want to move to the positive terminal (protons don't move because they are in the center of an atom). The only thing stopping the electrons from jumping to the positive terminal is air because it has a lot of resistance.Resistance is how hard it is for electrons to move through a material. Copper wire has a very low resistance, so when you connect the two terminals together with wire, electrons start moving across the wire from the negative terminal to the positive terminal. Electrons move slowly across the wire, but they start a chain reaction in the atoms that make the wire so that now almost all the atoms want to give some of their electrons to the positive terminal. This reaction moves very fast, almost at the speed of light, and that's things power up almost instantly once they are connected to a power source even though the electrons themselves move slowly. The movement of these electrons is called current, and that's what powers electric devices.
Howdoes Electricity flow through a wire?
Electricity flow through a wire as a result of the movement of electrons and hols.
How is current carried through a wire?
Current is carried through a wire by the flow of electrons. When a voltage is applied across the wire, electrons move from the negative terminal to the positive terminal, creating an electric current. The movement of electrons creates an electric field along the wire, allowing for the flow of current.
What carries electricity through a wire?
Electricity is carried through a wire by the flow of electrons. When a voltage is applied across the wire, the electrons move in response to this, creating an electric current that can power devices or light bulbs.
What happens when electricity flow through wires?
Electrons move through the wire
