I have a very basic electrical question that I have not been able to discover the answer to. Most of us have probably seen a scene in a movie/tv show where someone sticks a metal object into a prong of an outlet and gets a severe shock. The example that comes to mind for me is an episode of the tv show House, "97 seconds" where multiple people in the episode get shocked by inserting a metal knife into a single prong of a wall outlet (individually, during separate parts of the episode). My understanding is that you are only going to get shocked unless current is flowing through you, and in order for that to occur there must be a conductive path for the electricity to flow from one terminal to the other of the source of voltage. It would make sense to me if someone was shocked by inserting a knife in each hand into each prong of the outlet, thereby completing the circuit through your body, but otherwise I do not see how it is possible. If it is relevant, you can address the case where the subject is wearing rubber soled shoes, and maybe another where they are barefoot and standing in a puddle of unpure water. (both cases only one knife in one prong of the outlet of course) Any info is appreciated, thanks! edit: I assume this has something to do with the path to ground, but I could use some clarification on the feasibility of that as in the scenario I mentioned it seemed like it would be distant enough to not be relevant.
