the metal ;-)
Metal consists - like every material - of protons and neutrons as a nuclei and electrons who orbit them. In a metal the nuclei are so near to each other, that electrons are able to 'jump' from one nucleus to another.
Take the earth as nucleus and the moon as electron. Now imagine, the mars would be so closed to the earth, that the moon is sometimes orbiting the earth and sometimes the mars.
That is ecactly what happens in metal all the time and that's why those electrons are called free electrons. Due to the fact that an electron is containing an electric charge, the the charge does move from one place to another.
So electrons carry the electric charge, while nuclei are not able to bond.

∙ 14y agoCurrent in a wire is carried by the lattice of electrically conductive atoms, each allowing electrons to jump from atom to atom, as the electron flow progresses through the conductor.
Due to the opposition of same-charged particles, the electrons will tend to congregate on the surface of the conductor, an effect called skin-effect, which means that the bulk of the current flow will be on the surface, particularly for higher voltages encountered in utility power distribution systems.

∙ 14y agoAll wires carry what every the line voltage is. How a wire carries electricity, without getting into electrical theory, is called the skin effect in which electricity travels on the surface area of a wire or conductor. Electricity is 'pushed' along by an effect called EMF or electromotive force.

The previous answer is very limited (and mostly wrong). Yes, the electric field can act on charges and give them energy, but it is giving away its own energy.
An Electric field itself represents a store of energy, where photons can carry energy from place to place (macroscopically, using the poynting vector). To convince yourself of this, consider a sharp discharge spark on a high voltage source. It sends off a bit of EM radiation into space. All charges involved in its production go into the negative terminal of the apparatus. The EM wave, however, will go off to infinity, carrying energy along with it.
The short answer to your question is that the electric field itself is a store of energy. The energy density at a point is given by the expression 1/2*(permittivity of free space)*E^2.

There are many kinds of atoms, but they all consist of a dense central structure called the nucleus around which negatively charged particles called electrons rotate. The flow of these negatively charged electrons within a material is called an electric current.

What is a current-carrying wire?
A wire with some resistance and a voltage applied to it The amount of current I passing this wire is V/R
What does the live wire do in an electrical circuit?
The live wire in the supply cable carries current from the power station to the electrical device that you want to use. The current returns to the power station through the neutral wire in the supply cable. For safety reasons, on some electrical equipment there is also a ground wire - also known as an earth wire. It is connected to any metal parts on the outside of the unit, such as a metal case, and to any internal metal chassis, motor framework, etc. The ground wire is necessary to conduct away the current which could otherwise kill someone if a fault or an accident happens which damages the insulation of the live wire so that it touches any of those metal parts and gives them a high voltage. That would be very dangerous to the human users of the equipment.
Lightning carries Alternating current or Direct Current?
Power lines carry electricity as alternating current.
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
What is the difference between neutral and earth wire in the distribution system?
Both conductors are at ground potential. They are connected together with a bonding jumper at the panel. The primary difference is the neutral is used as the return current path for single-phase loads, and the ground is the return path for fault current only. So, unless the hot conductor accidentally comes in contact with, say, a grounded equipment cabinet, there would be no current flow on the ground wire. The neutral wire carries current any time the single-phase load is in operation. With a three-phase balanced load, no neutral is necessary or required, yet electrical codes still require a ground wire for safety.

What is black wire use for?
In household wiring it is the "hot" wire that carries current to the load.
What happens to copper wire because of the moving magnet?
The copper wire carries an electric current.
Do wires electromagnetic?
Any wire that carries a current will have a magnetic field.
Why the current coil of wattmeter has more thikness wire than pressure coil?
Current coil carries the current.
What carries messages by wire?
A machine for preserving food cold and fresh
A wire carries a current of 6.0 amperes How much charge passes a point in the wire in 120 seconds?
720 C
Is a ground wire necessary for a complete circuit?
No, the ground wire is there for safety reasons and only carries current in fault conditions.
Does the gauge of a wire change the amount the energy it carries?
It determines the amount of electric current it can safely carry
What devices get a neutral wire?
All devices use two wire, the live and the neutral. These carry the current used by the device. Most devices also have an earth wire for safety, which carries no current until a fault occurs and then the fault current in the earth wire might save someone from being electrocuted.
If a long straight wire is aligned northsouth and carries current in the northerly direction What is the direction of the magnetic field created directly above the wire?
east
What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?
The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.
