Hints for Test I
- As usual we should have time the day before the test to review
for the test. Come to class with questions! (Stump the instructor day!)
- No sheet of equations.
- Constants will be provided, as will equations needed from last
semester.
- You must show the instructor an empty calculator memory before
the test starts.
- Any interesting material from these chapters or the labs
not covered in class is a possible bonus question.
Hints for test I !?
- You should know how to find the electric field using Coulomb's
formulation or Gauss' law. This means:
- Knowing how to decide when to use which law.
- Knowing how to add vectors if there is more than one source of
electric field.
- Knowing how to integrate on a surface.
- You should be able to find the magnetic field using Ampere's law
or the law of Biot-Savart. This means:
- Knowing how to decide when to use which law.
- Knowing how to add vectors if there is more than one source of
magnetic field.
- Knowing how to integrate on a line.
- Knowing how to work with a cross product.
- Obviously you will want to review the problems we did in
class, homework problems, and examples in the book. You may want to
look at
the homework solutions I have posted; even if you got a problem right
the
solutions may show you a short cut or clever trick. Plus: extra
credit
for the first person to point out an error in the solutions to me.
- Potential bonus questions may include questions from the lab:
- What is Ohm's Law?
- What is the difference between resistance and
resistivity?
- What are Kirchoff's rules?
- The following are extremely likely:
- One electric force/field problem (vectors!).
- One magnetic force/field problem.
- One Guass' law problem.
- One Biot-Savart problem.
- One Ampere's law problem.
- One torque on a magnetic moment problem.
Past tests.
- From year to year we cover slightly different material so you
may see things in past years that were not covered this year.
Conversely you may
see things on this year's test not covered in previous years.
- Due to limitations with html formatting, not all figures and
equations are available.
