All six units of the calculus-based AP Physics C: Electricity and Magnetism course framework. They are numbered 8 through 13, continuing from Mechanics rather than restarting at 1, because that is how the College Board numbers them: the two Physics C courses share one framework. Approximate weightings are from the College Board Course and Exam Description; exact weightings vary year to year.

Coulomb's law as a magnitude plus a direction, conservation of charge through friction, contact and induction, electric fields and what field lines do and do not mean, fields of continuous distributions by integration, electric flux, and Gauss's law.
Electric potential energy and potential, the difference between them, the field as the negative gradient of the potential, equipotentials, and energy conservation for charges moving through a field.
Conductors in equilibrium, cavities and shielding, charge redistribution between connected conductors, capacitance as a geometric constant, series and parallel combinations, stored energy, and dielectrics.
Current and drift speed, simple and compound DC circuits, resistance and resistivity, electric power, Kirchhoff's loop and junction rules, internal resistance, and RC transients.
Magnetic fields and what they act on, the force on moving charges and current-carrying wires, the field produced by currents via the Biot-Savart law, and Ampere's law where symmetry allows it.
Magnetic flux, Faraday's law and Lenz's law, motional EMF and induced forces, inductance and back-EMF, LR transients, and LC oscillation.
All 31 topics ship with a misconception-targeted lesson and a ten-scenario skill check, built on a taxonomy of 114 documented errors. Diagnostics, targeted drills and cumulative exams are being authored against that same taxonomy and are marked "Coming soon" until they are live.
