Copied from a post in an internet usenews newsgroup (rarp):

Most electricity is manufactured at power stations and stored in wire. The
wire is then wound on large spools for transport. Not all forms of
electricity need wire to get from one place to another. Electricity used
for lightening and portable radios are examples. This kind of electricity
is just laying around in the air already.

Electricity made at power plants makes a humming noise that can be pitched
differently for things like doorbells, telephones and electric organs.
Electricity can be ordered if different colors for use in neon signs,
Christmas Trees and stuff like that.

Electricity also comes in different lengths, Long and Short. If you use
long where a short should be used it just last longer. However if you use a
short where a long should be used, it makes smoke. Usually electricity has
to be connected to the ground to work properly. The exception is in
airplanes, which special arrangements have been made for.

Boats are grounded via the prop shaft to and water. Since saltwater
conducts better then freshwater, boats can go faster in the ocean than on a
lake. However if they go to fast they jump out of the water, thus loosing
the ground connection and immediately fall back into the water. Electricity
is made of two ingredients. One travels in wire that is covered by black
plastic. The flows in wire covered with white plastic. These ingredients are
mixed at a wall plug to make consumer grade electricity.

Portable electricity is stored in batteries. Large batteries do not
necessarily hold more electricity than small ones. Electricity is just piled
in a haphazardly in a large batteries. However, in transistor, watch and
calculator batteries, the electricity is stacked in neat and orderly
fashion.

Light switches are simple clamping devices that squeeze the wire hard enough
to stop the flow of electrons. Light from light bulbs is produced by having
two uncovered wires in close proximity to each other. Electricity applies
the spark between the two uncovered wires. The effect is then magnified
hundreds of times by the curved glass bulb, thus making enough light to
light up a room. One would think that light bulbs would last indefinitely.
However it converts oxygen to water. When all the oxygen in the bulb is
converted to water, the arc is quenched and the bulb must be thrown away
because water & electricity cant be homogenized.

There is really only one brand of fuses and that company has been in
financial trouble for years as evident by their practice of making the fuse
wire too thin.Fuses are an unnecessary evil. We have them because the fuse
company's brother is a member of congress and he passed a law that says
everyone they have to use fuses. In the old days we just ties the wire
together with square knots in a junction box. Electrical appliance burst
into flames if the switch fails in the "on" position thus lettings too much
electricity in.

Brilliant! [Linked Image]

But I thought that the white wire supplied nice clean power to the appliance, and then by the time the 'lectric'ty had done its job it was all dirty, so it goes back along the black wire! The green wire supplies ultra-clean "environmentally friendly" electrons for special equipment, doesn't it? [Linked Image]

Finally, an explanation I can understand. Thank you.
