I was looking for a water well service in the area and came across this interesting document. An excerpt:
1. ELECTRICITY A. Principle 1: Electricity is tiny peas. They are hard to see because they are so small and move so fast, however, they are green. (OK, you guys at Argonne National Labs - prove I'm wrong!)
B. Principle 2: The speed of the peas is measured in volts.: The speed of the peas is measured in volts. This can be converted to miles per hour, or furlongs per fortnight if so desired, but volts are nice and tidy.
C. Principle 3: The number of peas is measured in amps. There are so many in a pound, it is inconvenient to weight them.
D. Principle 4: The power the peas have is the number of peas multiplied by their speed. This is just how hard the peas hit. Same principle as getting hit with a water hose.
A. An electric motor is a machine to get useful work from electricity. It is also two magnets chasing each other, with one magnet tied to a rotating shaft, while the power company changes their polarity just when the north and south poles start to line up. (This is somewhat cruel but necessary. It is something like dealing with a woman.)
B. Some people think motors run on smoke because when the smoke gets out, they stop working. This is not true.
