Hints!?

• Bring your own sheet of equations.
• Constants will be provided.
• You must show the instructor an empty calculator memory before the test starts.
• Problems will include the following concepts:
  • Coulomb's force law.
  • Electric field due to several point charges.
  • Force on a charge 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.
  • Both of Kirchoff's rules.
  • Resistors in parallel and series.
  • Resistivity and temperature variance of resisance.
  • Electrical energy and power (household circuits).
  • Magnetic force on a moving charge and/or magnetic force on a current carrying wire.
  • Magnetic field of a long wire and/or loop of wire and/or solenoid.
  • Torque on a current loop.
  • Faraday's law and Lenz's law.
  • No problems on peak, instantaneous and rms voltages and current (we skipped this part).
  • No problems about capacitive reactance, inductive reactance and or impeadence in an AC circuit (we skipped this part).
  • No problems on electrical resonance (we skipped this part).
  • Power in an AC circuit, transformers.
  • Frequency, wavelength and speed of electromagnetic waves.
  • Snell's law and the index of refraction including total internal reflection.
  • Spherical mirrors and thin lenses of all types.
  • Diffraction and interference.
  • No nuclear physics (alpha, beta gamma decay; fission and fusion).
• Review questions from the three tests this semester! I will have the three in-class tests in front of me as I make out the final.
• Review the problems we did in class and examples in the book. The problems with a square around them (worked out in the student guide) are good review problems.
• Any interesting material from these chapters not covered in class is a possible bonus question. Potential bonus questions may include:
  • One or more quiz question from the quizzes this semester.
  • A question about one (or more) of the labs.
  • A previous bonus question from one of the three tests.

GOOD LUCK!
