When I see an electrical arc ,what am I really seeing?

  1. Apr 12, 2008 #1
    When an electrical arc occurs, is the blue/white/purple arc the electricity itself, or is it a result of the electricity interacting with something in the air?

    You are seeing ionized gases in the air radiating EM energy. Try this one!

    You cannot "see" electricity because that's what facilitates the whole "seeing" thing. As said you're looking at its result.
