There are two AP Physics C courses — Physics C: Mechanics and Physics C: Electricity and Magnetism. According to surveys of comparable curricula at four-year colleges and universities, each of these courses corresponds to a one-semester introductory calculus-based college physics class. Physics C: Electricity and Magnetism provides instruction in electrostatics; conductors, capacitors and dielectrics; electric circuits; magnetic fields; and electromagnetism.

The Physics C course also includes a hands-on laboratory component comparable to a semester-long introductory college-level physics laboratory. Students spend a minimum of 20 percent of instructional time engaged in hands-on laboratory work.

Topics covered on the exam include:

Electrostatics (30%)

  • Charge and Coulomb’s law
  • Electric field and electric potential (including point charges)
  • Gauss’s law
  • Fields and potentials of other charge distributions

Conductors, Capacitors, Dielectrics (14%)

  • Electrostatics with conductors
  • Capacitors
  • Dielectrics

Electric Circuits (20%)

  • Current, resistance, power
  • Steady-state direct current circuits with batteries and resistors only
  • Capacitors in circuits

Magnetic Fields (20%)

  • Forces on moving charges in magnetic fields
  • Forces on current-carrying wires in magnetic fields
  • Fields of long current-carrying wires
  • Biot–Savart law and Ampere’s law

Electromagnetism (16%)

  • Electromagnetic induction (including Faraday’s law and Lenz’s law)
  • Inductance (including lr and lc circuits)
  • Maxwell’s equations
