15–18% of the AP exam. Key topics: Coulomb's law (F = kq₁q₂/r²), Electric fields from point charges and charge distributions (E = kq/r²), Superposition principle for electric fields and forces, Electric potential energy (U = qV), Electric potential (V = kq/r) and the distinction from potential energy, Equipotential surfaces and their relationship to field lines, Capacitors: definition, capacitance (C = Q/V), energy stored, Charge distributions on conductors (surface charge, shielding), Conductors vs. insulators in electric fields, Gauss's Law (conceptual application).
