I would assume that the speed is higher than the speed of light, as experiments by Goudsmidt and Uhlenbeck in the mid 1920s showed the electrons spin (orthorotates) 1,7 times the speed of light - assuming ressonance occurs, the electrons absorbing the sound wave (at the microphone) ressonate with the electrons emitting the wave (at the speaker) and the sound is transfered 'imediatetely' through quantum ressonance.
If the sound travelled with the electrons, the sound would travel 2-3 cm per sec. This does not happen. The sound waves probably are not transformed to photons - travelling at light speed - if that were the case, how could the copper core in an insulated wire (rubber or plastic) absorb the photons? Nor are they transformed to other quarks or elementary particles.
This is an example of electron ressonance, the electrons absorb, transmit and recieve the physical wave of sound from one part of the copper wire to the next. This ressonance ensures that the speed of light is ecceded. The sound travels in the form of rotating electrons in ressonance in the two parts of the wire.

∙ 14y agoIt's actually a light signal that travels through a fibre optic cable. The speed is the speed of light divided by the refractive index of the material. This works out to around 200 million metres per second.
A rough rule of thumb is 18 inches per nanosecond.

∙ 13y agoI have read elsewhere that electricity effectively travels at the speed of light (approx 186 miles per second). It would follow then, that if you connect a battery to a bulb with a one light year long wire (and back to the other terminal with another such wire), when the circuit is connected, the bulb should light in a years time. The wires involved in this senerio, however, are about 6 trillion miles long. For any house wiring job, when the switch is operated, the bulb should come on at once. In brief, how fast does electricity travel down a copper wire? Lightening fast.

∙ 12y agoAbout 2/3 the speed of light in a vacuum. I have seen a speed of 0.68 c used in calculations, but this may be approximated as 2/3 c.

Does electrical energy travel through wires?
An electrical current - and the energy it carries - can travel through any conductor. Quite often, these conductors will be wires.
Does electrical energy travel as waves?
Electromagnetic energy travels by waves. These waves can travel through space and through many types of matter. Electrical energy of sufficient voltage can arc through space and some matter (lightening for example). More commonly, electrical energy travels through conducting media such as wires of copper. AC electricity could be considered a wave, but not in the same sense as electromagnetic energy.
How does electricity travel from one place to another?
Electricity usually travles through wires, but it can also travle through short spaces in the air.
Why are copper wires used as the connecting wires?
Copper is a metal and as such it can conduct electricity very well. Additionally, copper is a very good conductor off heat when compared to the more abundant metals such as aluminium.
Why does thin wires have high resistivity than thick ones?
Less surface area and cross section for the current to travel through.
What did the cell phone develop from?
it developed through copper wires
What flows through copper wires in electricity?
Anions and cations..
Does electrical energy travel through wires?
An electrical current - and the energy it carries - can travel through any conductor. Quite often, these conductors will be wires.
How does electrical energy travel?
Through electrical wires.
Can electric charges travel through wires?
Electric charges can travel through solids, liquids, or gases. They can travel through conductors, insulators, and semiconductors.
Can electric charges only travel through wires?
Electric charges can travel through solids, liquids, or gases. They can travel through conductors, insulators, and semiconductors.
How does information travel through the medium of electrical wires?
it is cool
How can electricity be transfered?
Electricitiy can be transfered through radiation.
Why are copper wires used instead of steel wires?
I think copper is cheaper.
What is the scientific word for when it is difficult for the current to travel through the wires?
resistance
Why electrical wires have plastic covering?
Electrical wires have plastic covering as when electric current flows through the copper wires and mistake we hold it so we may get an electric shock.
How does music travel to headphones?
Music travels to headphones through the wires in their cord.
