    Undergrad How conductive is ionized air from a plasma cutter spark?

    So I've been reading about how plasma cutters work, and the way it ignites intrigued me and got me thinking. My question is, how conductive would a stream of ionized air created by a high voltage spark be? If you passed a high current, low voltage through the stream, would it be able to travel...

    How is an RF signal generated from AC current?

    Thanks for the response! I tried looking up your direction, but still got very lost. It makes sense what you're saying, but I can't find much on it. Like, if I were to short the neutral and hot wire on 120v mains, I know there'd be an explosion. If it's oscillating at a higher frequency, does it...

    How is an RF signal generated from AC current?

    Okay, sorry for my frustration at this fundamental subject, but I am going completely insane not understanding it! All this near-field / far-field stuff is messing with my head. I simply want to know how RF works. Let's start simple. HOW IN THE WORLD IS AN RF SINGAL MADE!? Let's say I have some...
