AP Physics C: Electricity and Magnetism Practice Test 1

This practice test contains 42 multiple-choice questions to be completed in 85 minutes, mirroring the length, timing, and 50% exam-score weight of Section I of the official AP Physics C: Electricity and Magnetism Exam. Each question offers four answer choices (A--D); select the single best answer for each item. Several questions share a common circuit description or field geometry presented immediately before the questions that reference it --- read each stimulus carefully before answering. Because this is a calculus-based course, a number of items require derivatives or integrals (Gauss's Law flux integrals, potential-to-field differentiation, RC/RL differential equations, Faraday's Law) rather than algebra alone. A scientific or graphing calculator is permitted throughout this section, consistent with AP Physics C Exam policy; $k=8.99×10^9 N·m^2/C^2$, $_0=8.85×10^-12 C^2/(N·m^2)$, $_0=4×10^-7 T·m/A$, $e=1.60×10^-19 C$, $m_e=9.11×10^-31$ kg. This is an independently written practice test created for study purposes and is not an official College Board form; it is not endorsed by or affiliated with the College Board or the AP Physics C Program.
