Electromagnetic waves in a perfect conductor [closed]

Webconductor: An electrical conductor is a substance in which electrical charge carriers, usually electrons , move easily from atom to atom with the application of voltage . Conductivity, in general, is the capacity to transmit something, such as electricity or heat. 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. smallwoods washington
