Re: Physics for Electricians

[William Beaty <billb@ESKIMO.COM>]

If you decide to explain physics conceptually, here's some online info
I've been accumulating:

Simple classroom activity.  Use red and green plastic sheets to visualize
Electric Current, "Static", and the electric charge which creates both.

There is a simple answer to this question.  Really.  Not the one you
expect, though:
  What Is "Electricity?"

Charge REALLY flows from negative to positive, right?    RIGHT???
  In a circuit, which way does 'electricity' actually flow?
  http://www.amasci.com/amateur/elecdir.html


Everyone is sure that charges flow in wires at nearly the
speed of light.  All the elementary schhol books say so, and that many
books can't be wrong, can they?  Ah, but science is not settled by
voting.
   Speed of "Electricity"?

Why I never really understood capacitors, even after many physics and
engineering courses:

Why do wall outlets have three holes?  "Grounding" and safety.
   Why three prongs?

Everyone learns about "Amps" but never remembers what a "Coulomb" is.
This is totally backwards:
  Are Amperes "Fundamental?"

Twenty misconceptions which prevented me from understanding simple
electrical science as a student.  Maybe they cause trouble for you as
well?

Not the usual answer found in most textbooks!
  How is "static" different from "current?"

How can so many textbooks and encyclopedias make a major mistake:
  Electricity is not a form of energy?!
  http://www.amasci.com/miscon/energ1.html


Use sticky tape to demonstrate the behavior of electric charge:
  Sticky Electrostatics

How are batteries different than static cling?  Perhaps this diagram
will "generate" some insights:

I'm always getting into flamewars about this stuff...
