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.

2. MOTORS

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.
