Hello,

Assumed you have a tiny voltage source, from a sensor. (like 0.3V).
This source is connected to a 0.25mm copper jumper wire.
The second extremity is connected to a voltage meter.
All the way from source, to the volt-meter, how this signals travels? What are the physical laws?
 


Your question indicates that you have no basic knowledge of electronics principles.

First you fail in defining the signal source and the signal. A signal source must be specified by its impedance , and a signal has not only a voltage but a frequency spectrum.

Connecting lines may be designed as TEM or other types, and propagating signals travelling along do not only pass through the conductor(s) but in the dielectric medium.

Go and read the basics of electronics!
