The speed of light is approximately 3x10^8ms (exactly 299,792,458 m/s), but electric signals don't travel that fast in conductors. They travel anywhere from 40% up to 95% of that speed, depending on properties of the cable (the dielectric constant of the material surrounding the copper is a big factor).
Twisted pair copper cabling used in telephone wiring tends to be on the lower end, somewhere between 40% to 70%. So a good estimate is somewhere between 120,000,000 m/s to 210,000,000 m/s.
(The drift speed of electrons in a wire is much slower, on the order of millimeters per second. Electric signals travel through conductors as an electromagnetic wave.)
What else can I help you with?
How does your voice go through a telephone wire?
it is first converted into an electric signal by your telephone, and then transmitted over the copper wire
Is a telephone wire copper?
no
What is telephone wire made of?
Copper
Who invented the telephone and copper wire?
dont know lego4699
What are telephone made of?
Mainly all telephone wires are made of copper with a plastic coating for insulation. Older form of telephone wire had a paper or pulp insulation over the copper wire. They are also a twisted pair cable.

What color is the wire of the speed signal for Chrysler town and country 2008?
There isn't a dedicated speedometer signal wire. The speed signal comes from the transmission computer and is sent on two way communication wires to the cluster.
How fast can sound waves travel in copper wire?
Sound waves can travel at a speed of around 4,920 meters per second in copper wire. This speed is dependent on the material properties of copper, such as its density and elasticity.
What type of wire is used to connect telephone to wall outlet?
Typically, twisted pair wire, specifically known as Category 3 or Cat 3 cable, is used to connect a telephone to a wall outlet. This type of wire consists of two insulated copper wires twisted together, which helps reduce interference and improve signal quality.
What are the components of telecommunication?
signal source+Transmitter+medium(copper wire, coaxial cable, air)+receiver
What materials could block a wifi signal?
aluminum foil and copper wire--but how does it block a cell phone's connection??-_-
The characteristic impedance of paired copper wire is?
The characteristic impedance of paired copper wire is typically around 100-120 ohms. This value is important in determining signal integrity and impedance matching in communication systems.
