It's kinda like a fire if there is nothing to burn the fire wont go there, so with electrons if there is nothing to travel in to (like a switch, a light bulb, a buzzer ect.) the electrons wont go there because they can't just travel through air like fire can't just travel through air.
What else can I help you with?
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.
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 is copper wire better conductor of electricity than a rubber tube is?
In rubber electrons cannot freely move among atoms as in copper.
Why electrons path is helical?
In a copper wire each copper atom has two loosely coupled outer thermal atoms (this is why copper has a plus 2 valence)When an electrical current is passed through the copper wire, the two thermal atoms are pushed onto the next copper atom. Temperature of a copper atom depends on how fast the electrons orbit in the respective copper atoms.Since thermal electrons make up the electric current which flows through the copper wire, the electrons will continue to orbit the copper atoms as they move across, thus travelling along a helical path
Would a copper wire act as the best insulator of electric current?
no it is good conductor because it has free electrons
How many electrons in copper wire?
Copper wire typically contains one free electron per atom, as copper has one electron in its outer energy level. So, the number of electrons in copper wire depends on the number of copper atoms present in the wire.
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.
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.
What copper wire would have the highest resistance?
A thicker copper wire will have higher resistance as it will offer more opposition to the flow of electrons compared to a thinner wire. Additionally, a longer copper wire will have higher resistance compared to a shorter wire due to increased distance for the electrons to travel. Finally, a copper wire with impurities or defects will have higher resistance than a pure copper wire.
What happens when copper wire is moved through a magnetic field?
A net force acts on the electrons in the copper wire ...the electrons move depending on the direction of magnetic field and the motion of the wire and henc e there will be a current in the wire
What happens to the resistance of copper wire as the temperature of the wire increases?
The resistance of copper wire increases as the temperature of the wire increases. This is due to the increase in collisions between free electrons and atoms in the wire, which hinders the flow of electricity.
When Electrons are flowing through a copper wire is an example of what energy?
Electrical energy.
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 happens to copper wire when heated?
When copper wire is heated, it expands due to thermal expansion. As it gets hotter, the electrons in the copper atoms move more freely, increasing electrical resistance. Excessive heating can cause the copper wire to melt and ultimately vaporize.
Is electrons moving through a copper wire an example of electric current?
Yes it is, when there's a large-scale average motion in one direction due to a voltage between the ends of the wire, and not just the random thermal motion in a piece of wire in the back of a drawer somewhere.
When does a copper wire produce a magnetic field?
A copper wire produces a magnetic field when an electric current flows through it. This is due to the interaction between the moving electrons in the wire and the magnetic field they generate.
Electrons flow freely through a copper wire is what?
An electric current flows when electrons move through a conductor like copper wire. The movement of the electrons is driven by an electric field applied to the wire, leading to the flow of charge and the generation of electrical energy.
