What do we exactly mean by charge and why the elementary …
Sep 24, 2020 · A coulomb is 6.241 x 10^18 elementary charges. But what exactly is a coulomb? And what do we mean exactly by a charge? how was it measured?
Why do we still call the electron charge the elementary (EM) charge?
Oct 19, 2019 · The electron is an elementary particle, part of the SM, pointlike, with no substructure, or spatial extent. Its intrinsic properties include its EM charge, which we still call …
Relationship between the bare charge and the elementary charge …
Jul 17, 2021 · Bare charge should be the charge of the particle without any quantum fluctuations, so we cannot measure it. For example, for an electron, how is this charge related to the …
Why do electron and proton have the same but opposite electric …
This would turn an approximate equality in an exact equality, and hence prove the equality of the charges of the proton and the electron (apart from the sign). Thus it would explain this …
Why do we have an elementary charge but no elementary mass?
@Lubos: So you are basically saying that we have an elementary charge, because magnetic monopoles exist and we have no elementary mass, because we measure a positive …
