Attenuation.
even a single wire can tansmitam signal in which ac signal pass through it
Crosstalk occurs in twisted pair wire when a current or signal in one wire can produce an unwanted current or signal. If the two wires run parallel to each other the chance for crosstalk increases. Mutual inductance is a consequence of an alternating current (AC) in one conductor developing a fluctuating magnetic field which induces current flow in another close-coupled conductor. In computer networking or communication, this is termed cross-talk. The signal in the source wire is mirrored (at a lower strength) in the other. Where two conductors run parallel to one another for long lengths, the cross-talk signal is additive and can be considered as noise, where the other conductor is carrying its own signal.
it is first converted into an electric signal by your telephone, and then transmitted over the copper wire
When an electric current runs through a loop of wire, it generates a magnetic field around the wire. This phenomenon is known as electromagnetism.
You can trace a wire without power by using a wire tracer tool that sends a signal through the wire, allowing you to follow its path using a receiver.
Crosstalk
When electricity runs through a coiled wire, the coil becomes an electromagnet. The magnetic field produced by the coil allows it to attract or repel other metals.
The oxygen sensor is connected by a wiring harness. The wiring harness contains the signal wire. The signal wire goes to the system computer.
Circuit
To trace an electrical wire effectively, use a wire tracer tool that emits a signal along the wire for you to follow. Follow the wire's path visually and listen for changes in the signal to locate the wire accurately.
