WebWhen you apply an electric field to a conductor, each electron only has to move a little bit, but all of them move together, and so the net current can be quite high. Signals propagate along wires at very high speeds. If a wire is perfectly conducting, then the speed of a signal propagating along depends on the insulating material around the wire. Web6 de jun. de 2024 · Because the signal itself is travelling due to the charges setup in wire and electrons have mass too and a very low drift velocity. In this way one electrons moves a little and it electric field propagates and then the next charge moves a little and and so on.
