Study Guide, Test 2

Test 2 will cover the material presented in modules 4-7.

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.
• Use Gauss' law to find the electric field produced by symmetric charge distributions.
• Calculate the potential difference between two points in space for various distributions of charged particles.
• Obtain the electric field when given 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.
• Use Kirchhoff's rules to analyze DC circuits.
• 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.
• State Ampere's law.
• Calculate the magnetic field produced by current carrying wires in simple geometric configurations.
• Qualitatively describe properties of magnetic materials.

Prepare for the test by reviewing assignments 9 - 16.

Please take the practice tests on Canvas.  You can take these tests as often as you want.  No score is kept.  Each problem contains hints for incorrect answers.

Formulas

During the test you can use a calculator, the formula sheet, scratch paper and copies of the fundamental constants and conversions provided on Canvas under course materials.
