Study Guide, Test 1

Test 1 will cover the material presented in modules 1-6.  The test is an 90 minute test and it allows one submission.  There are 30 problems.  You can omit 5 problems or you can answer all problems and the best 25 answers count.  The highest score you can get is 25/25.

You must be able to:

• State Coulomb's law.
• Use Coulomb's law and the principle of superposition to find the electric force between charged particles.
• Use Coulomb's law and the principle of superposition to find the electric field produced by charged particles.
• Calculate the potential difference between two points in space for various distributions of charged particles.
• Estimate the electric field when given plots of the potential.
• List the properties of conductors in static situations.
• Find the capacitance of capacitors in series and in parallel.
• Define current density, current, resistance, and resistivity.
• Solve simple circuit problems involving voltage, current, resistance and power.
• Find the equivalent resistance of resistors in series and in parallel.
• Calculate the magnetic force on moving charges and current-carrying wires in a uniform magnetic field.
• Calculate the torque on a current loop (magnetic dipole) placed into a uniform magnetic field.
• Calculate the magnetic field produced by current carrying wires in simple geometric configurations.
• Qualitatively describe properties of magnetic materials.
• Correctly analyze situations in which an emf is induced by a changing magnetic flux.
• Calculate the magnitude and determine the direction of the emf induced in simple circuits.
• Explain the concept of self inductance.
• Explain how devices such as electric generators, transformers, magnetic brakes, etc, work, based on Faraday's law.
• Explain how electromagnetic waves are produced and how they transport energy and momentum through space.
• Identify different regions of the EM spectrum.
• Distinguish between unpolarized and polarized light.

Prepare for the test by reviewing assignments A1 - A6 and H1 - H6 and the problems on the summary slides.

Please take practice test 1 on Canvas.  You can take this test as often as you want.  No score is kept.  Each problem contains hints for incorrect answers.

Formulas

The first page of test 1 is the formula sheet.  During test 1 you can use this formula sheet, but you can also use other printed (on paper) reference materials of your choice.  You however must work alone.  Please do not consult with another person while you are taking the test.
