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.

What size of electrical wire needed for 100A circuit breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated for 105 amps.
What is the predominant carrier of electrical charge in a copper wire?
Electrons are the predominant carriers of charge in copper wire.
Why a copper wire in a closed circuit does not get heated?

What size wire and circuit breaker is needed for an electric oven 4 wires with rated load of 34.9 amps 220v that is about 100 foot run from the electrical panel?
That would be a 40 amp 220v circuit. Circuit breaker is 40 amps and wire is 8 awg. Should use solid copper wire. Follow oven installation instructions.
What is the smallest copper wire size permitted by the national electric code for a 20 amp single phase electrical circuit?
I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.
Why does an electrical circuit have a copper wire?
If you mean a bare copper wire, that is the "ground" wire.
What are some substances in an electrical circuit?
Mainly copper for the wire, pvc for the insulation.
Why is copper used to connect wire in mobile phones?
copper is used because it is an electrical conductor which makes the electricity flow around the whole circuit.
What color is a ground wire in an electrical distribution?
The main electrical ground wire is sized to the service and is non insulted bare copper. Branch circuit grounds are green in conduit installations and bare copper again in house wiring cables.
Where does the wire come from in an electrical circuit?
The wire comes from the installer or manufacturer of the circuit.
What mineral are in electrical wire?
Copper!
What job does a wire do in a circuit?
The wire in a circuit helps to pass power to the electrical appliances.
What size of electrical wire needed for 100A circuit breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated for 105 amps.
What is the predominant carrier of electrical charge in a copper wire?
Electrons are the predominant carriers of charge in copper wire.
What type of electrical circuit will be broken if a wire breaks?
Current will cease to flow in a series electrical circuit.
Why a copper wire in a closed circuit does not get heated?
