Interesting discussion as it brings back a limited amount of my electrical engineering courses.

What happens to you if you are floating in water (a swimming pool for example or a big bath) and someone chucks in an electric fire or hair drier (see Hollywood) connected to the mains? Surely you would not be the least resistant part of any resultant circuit so should be fairly safe. Is this correct? (And no, I'm not willing to test it under any circumstances!!!)

Also, having recently watched What Women Want on the TV over the holidays Mel Gibson's character is shown drying his hair with a hair drier and falling into the bath gets a shock (fair enough as he is obviously part of the circuit mains, drier, Gibson, water, bath to earth). However do American bathrooms have mains sockets? In the UK and in Europe, the only sockets we are legally allowed in bathrooms are 110V (rather than the 220V mains) an are for electic shavers and there is no connection with the mains. As I understand it basically the electric current is induced so there is no connection between earth and the electric shaver.
