ELECTROSTATICS / ELECTRICITY TEST ON MONDAY, DECEMBER 18:

Be prepared for a test question on the following:

For the devices (listed below) which operate on the principles of electricity or electrostatics, describe how each works.   Choices on the test will include some of:
  1. electrostatic precipitator (or electronic air cleaner)
  2. lightning cloud
  3. Dry cell battery (how does it differ from a wet cell?)
  4. Lightining rods to protect buildings.


I will review your understanding on these concepts during Thursday's review.   I will check your completion of these on Thursday but these will not be handed in.
