Quick lesson in basic electricity (from Dave Barry):
Electricity is actually made up of extremely tiny particles, called
electrons, that you cannot see with the naked eye unless you have been
drinking. Electrons travel at the speed of light, which in most
American homes is 110 volts per hour. This is very fast. In the time
it has taken you to read this sentence so far, an electron could have
traveled all the way from San Francisco to Hackensack, New Jersey,
although God alone knows why it would want to.
The five main kinds of electricity are alternating current, direct
current, lightning, static, and European. Most American homes have
alternating current, which means that the electricity goes in one
direction for a while, then goes in the other direction. This
prevents harmful electron buildup in the wires.
