202 Test I

Topics covered:
- Electro-statics (Chapter 15)
- Electric potential (Chapter 16)
Time, date, place: 5:40 PM; Feb. 10 (date changed due to snow), 1998; PS106

No sheet of equations.
Constants will be provided.
You must show the instructor an empty calculator memory before the test starts.
Any interesting material from these chapters not covered in class is a possible bonus question.
The test will be mostly word problems with a few concept questions sprinkled into the problems.
Review the examples in the text and all the problems we did in class (both on the board and in small groups). Also the problems with boxes around them (indicating they are worked out in the student manual) are good to practice on. Try to work them before looking at the solution, then check to see if you've done it correctly.
You can expect at least one problem on each of the following:
- Coulomb's force law.
- Electric field due to several point charges.
- Force on a charge (or charges) in an electric field.
- Absolute electrical potential due to several point charges.
- Work done (or energy stored or potential difference) by moving a charge in an electric field.
- Definition of a capacitor and capacitance (with or without a dielectric).
- Adding capacitors in series and parallel.
- Energy stored in a capacitor.
On Feb. 3 we will review for the test. It will also be 'stump the instructor day' so bring your favorite problem(s) or question(s) from this material and watch the instructor sweat!
Potential bonus question topics:
- Cells as capacitors.
- Dielectrics
- Electrostatic percipitator
- Cathode ray tube
- Millikan oil-drop experiment
- Xerography
- Stud finder
