Timeline for If metals can’t sustain an electric field inside them (as their electrons move to cancel it out), how do they still conduct electricity?

| Apr 14 at 11:30 | comment | added | Zaph | @AaravRaj I have not read that much literature on that stuff myself so I can’t really tell you form personal experience, but I would suggest you look at some of the standard theory books for electrodynamics. For example the one by Fließbach or the one by Landau and Lifshitz or the one by Schwabl or any other really. | |
| Apr 14 at 11:24 | comment | added | Aarav Raj | Thnks for letting me know , can you please add some more resources where can i get more information, 1st year students trying to figure out how electric field works in some depth . Can you please tell some books where can i find some basic level theory of electruc field. Thank you. | |
| Apr 14 at 11:20 | comment | added | Zaph | @AaravRaj As for the details, that stuff is really complicated and an active field of science. To get an idea of how complicated it is, you might take a look at “Quantum Theory of the Electron Liquid” by Gabriele F. Giuliani, Giovanni Vignale. That thing surely will contain all the available information you might be interested in, when it comes to systems of charges reacting to external perturbations, and a lot more. | |
| Apr 14 at 11:18 | comment | added | Zaph | @AaravRaj Well the easiest way to think of it is, that the movable charges need some time to react to a perturbation of the equilibrium configuration caused by an external field change. As a result of the reaction, there will be some currents and if the perturbing fields then stay constant and you have some damping effects in your system you will eventually end up in a new static equilibrium situation, where no forces act on your charges, which means your charges are screened form the fields. | |

| Apr 14 at 7:09 | comment | added | Aarav Raj | Can you please explain a bit, how things go in dynamic situation or atleast tell me any resource where can i learn more about it. | |
| Apr 12 at 12:00 | comment | added | Zaph | @AaravRaj That statement of yours is only true, if the electrons in the metal have enough time to react on the field. In a static or slowly changing situation this will be the case, in a dynamical situation this will not necessarily be the case. | |
| Apr 12 at 8:38 | comment | added | Aarav Raj | How can electron flow without having an electric field, as my book says electric field can't go through conductors , even electric charge of a conductor resides entirely on the outer surface. | |
