Can anyone provide a good reference (preferably on-line), or a decent description, of how the fundamental constants of electromagnetism are experimentally determined?
I'm talking about constants like the permitivity and permeability of free space. I'm also curious how the unit of charge (coulomb) is defined experimentally. Perhaps more how the "standard of measurement" for the coulomb is defined -not how the fundamental charge on an electron was determined (I've got that one!).
(Also, I've seen in other posts use inset math typesets, which I would like to do here but I don't know how! Can anyone provide some guidance for this as well?)
Thanks in advance
