I believe that we can thank Mr. Tesla for the choice of 110V-60Hz AC =
along with Fluorescent lights, polyphase induction motors, radio, . . . =
and of course the Tesla coil.

The threshold voltage is very different for AC & DC voltages, as was
demonstrated by Thomas Edison. He electrocuted many dogs in an effort =
to
prove that AC was only good for killing; AC currents are far more lethal
than DC. (Some claim that these experiments gave birth to the idea of =
the
electric chair.) I believe that, for AC, the dangerous level is around
70-80 V, so typical household wall sockets can be dangerous; 110 V is a
rather odd choice from that perspective.
