The AC current tend to flow on the surface of the conductor. The higher the frequency, the thinner the skin.
This is known as the skin effect. So DC current flow throught the entire conductor but when the signal varies (AC) there is the formation of eddy current in the conductor itself and that pushes the electrons at the surface of the conductor.
You can get more information on the skin effect and skin depth on wikipedia :

Electric current can flow through the entire volume of a copper conductor, not just on the surface. This is due to the free electrons within the conductor that can move throughout the material and carry the current. The skin effect, which causes higher frequencies to flow more on the surface, is typically only significant at very high frequencies.

Is copper a good conductor of electric current because its atoms are made up of more electrons than protons?
Yes, copper is a good conductor of electric current because its atoms have loosely bound electrons in the outer energy levels, which can move freely between atoms when a voltage is applied. This flow of electrons constitutes an electric current.
Would a copper wire act as the best insulator of electric current?
no it is good conductor because it has free electrons
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.
Which type of soild is likely to be the best conductor of electric current?
GOLD IS THE VERY BEST CONDUCTOR, but for the money copper is better than aluminum and worth the extra cost.
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.
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.
What metal is a good conductor of thermal energy and electric current?
aluminum, copper,
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.
What and a conductor through which electric current travels through?
A conductor is a material through which electric current can easily flow. Metals like copper and aluminum are commonly used as conductors due to their high conductivity. When a voltage is applied across a conductor, electric charges move through the material, creating an electric current.
What is a material that will carry an electric current called?
A material that will carry an electric current is called a conductor. Conductor materials have high electrical conductivity, allowing the flow of electric charges with minimal resistance. Examples of conductors include metals such as copper, aluminum, and silver.
Will copper carry a electric current?
Yes, very easily. Copper is an excellent electrical conductor.
What is the path that an electrical current travels?
electric current
What element is a good conductor of electric current?
Copper is a good conductor of electric current due to its high electrical conductivity. It is commonly used in electrical wiring and circuitry because it allows electricity to flow with low resistance.
Is copper a good conductor of electric current because its atoms are made up of more electrons than protons?
Yes, copper is a good conductor of electric current because its atoms have loosely bound electrons in the outer energy levels, which can move freely between atoms when a voltage is applied. This flow of electrons constitutes an electric current.
Would a copper wire act as the best insulator of electric current?
no it is good conductor because it has free electrons
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.
What is the advantage of using a stranded copper conductor over a solid copper conductor?
It would of course depend on the specific application. Current tends to travel on the surface of a conductor and a stranded conductor has more surface area and thus offers less resistance to the current. Stranded wire also bends a bit easier than the corresponding size solid wire.
