None of the images load.
And so, i do not know if you are discussing Maxwell's equations or Heavyside's equations.
Since many images seem to have "wikipedia" in there titles, and the distinction between the two is not mentioned, than this discusses Heavyside's equations.
This is just an archive of the wikipedia page: https://en.wikipedia.org/wiki/Maxwell%27s_equations
