I am holding a plug, which is supposed to plug into a wall socket.
One of the two metal prongs is wider, so that the plug only fits one
way - not if you turn it over. Why is this? I thought the whole point
of AC was that the poles change sinusoidally; so how can one be
different from the other? Please direct replies to
