Steady currents are usually the realm of magnetostatics, but I don't know what best to call it if you're only concerned with the E-field, perhaps a special case of electrodynamics. What is important is that all fields in this case are static, and this means you can use Coulomb's law to calculate the E-field due to a fixed charge distribution even in the presence of DC currents. | |
| Mar 3, 2020 at 17:18 | comment | added | Kinka-Byo | Hello, I have a pair of questions which are similar to that I asked in this topic. Is the coulomb law for electric field (E = k Q/r^2) true also in electrodynamics (Q = Q(t))? Moreover, consider a conductor which is supplied with a DC voltage: are we in electrostatics (since current is constant in time) or electrodynamics (since charges move)? | |
