AP AP Physics C: Electricity and Magnetism Past Papers

The 2025 AP Physics C: Electricity and Magnetism Free-Response exam features the new 4-question format (40 marks total, 100 minutes) comprising Mathematical Routines (MR), Translation Between Representations (TBR), Experimental Design and Analysis (LAB), and Qualitative/Quantitative Translation (QQT). Performance was strongest on TBR (Question 2) and Lab Analysis (Question 3), while the multi-step calculus derivation for cylindrical capacitance and Gauss's law (Question 1) proved to be the most demanding.

The 2024 AP Physics C: Electricity and Magnetism FRQ examination placed heavy emphasis on graphical literacy, calculus-based derivations from first principles, and experimental protocol in RL circuits. With a global mean score of ~6.1–6.8 out of 15 across the three questions, students found multi-step derivations and piecewise graphical interpretations of magnetic flux and induced currents the most challenging.

The 2023 AP Physics C: Electricity and Magnetism Free-Response Examination evaluated core competencies across electrostatics, motional electromagnetic induction, and complex multi-state RC circuits. Question 1 focused on experimental design, Coulomb force balancing, graphical linearization, and conductor polarization. Question 2 assessed Faraday's law, motional emf, and dynamic braking forces with qualitative and graphical kinematics. Question 3 probed transient and steady-state RC circuit behaviors, differential equations, and energy conservation across capacitor charge redistribution. Overall, Question 1 saw higher accessibility (mean 7.64–9.67 / 15), while Question 3 proved the most challenging (mean 4.58–4.67 / 15) due to multi-step energy accounting and differential formulations.
