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 is the predominant carrier of electrical charge in a copper wire?
Electrons are the predominant carriers of charge in copper wire.
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
Why is copper wire better conductor of electricity than a rubber tube is?
In rubber electrons cannot freely move among atoms as in copper.
What are the elements in a copper wire?
If the copper wire really is pure copper then the only element in the copper wire is copper (Cu).
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 is a metal element. There are 29 electrons in a single atom.
What is the predominant carrier of electrical charge in a copper wire?
Electrons are the predominant carriers of charge in copper wire.
Electric current in a copper wire is normally composed of what?
Electron current in a copper wire is normally composed of electrons.
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 when a piece copper wire is heated in the outer region of the flame until its red hot?
The copper wire glows red. Once it cools...the copper reacts with the air to produce copper(II) oxide. This is shown by the black tarnish on the copper wire.
What is in an electric wire?
An Electrical wire is used to flow the electrons from one point another point . Copper or aluminum is insulated with polythine is called wire
Why is copper wire a good cunductor?
Copper is a very good conductor because most of its valence electrons take part in conduction.
Solid copper wire is a good conductor because?
The outermost shell of electrons in a copper atom is not bound to the individual atom (nucleus), but can move freely within the copper. So when attracted by a positive voltage, electrons can move toward it.
Why is copper wire better conductor of electricity than a rubber tube is?
In rubber electrons cannot freely move among atoms as in copper.
How does copper conduct electricity?
Copper conducts electricity by "musical electrons" like other conductors do. Let's look at copper and see what's up. Copper atoms in a copper wire all form some kind of metallic crystal structure. Not all the electrons in the valence shells of the copper atoms are "locked in place" in this structure. They are free to move around, and are said to be "free electrons" in this application. As they are not "bound" in the structure, the electrons can be made to move fairly easily. They can contribute to current flow. If we apply a voltage across the wire from end to end, electrons will enter one end of the wire and electrons will emerge from the other. Not the same electrons, mind you. Put some in one end, some come out the other. It could also be said that some of the electrons of the copper are at Fermi energy levels that are in what is said to be the "conduction band" for copper. The conduction band is the minimum energy level necessary for electrons of a given material to be in to support conduction in that material. If the Fermi energy levels of the valence band electrons is up in the conduction band, then that material is a conductor. Copper is this way.
You have copper and silver speaker wire and the silver has writing on it Which one is positive?
It is traditional to use the copper colored wire as the positive. Of course, the electrons don't care what color the wire is as long as you hook it up the same at both ends!
