The AP Physics C: Electricity and Magnetism exam is a rigorous, calculus-based assessment designed to be equivalent to a one-semester, introductory college-level course for physics, engineering, or physical science majors. It tests a student's deep understanding of the fundamental principles governing electric and magnetic fields and their interactions. The exam focuses on applying differential and integral calculus to solve problems in electrostatics, conductors, capacitors, dielectrics, electric circuits, magnetic fields, and electromagnetism. Students who succeed on this exam demonstrate not only mastery of core physics concepts but also the mathematical maturity to model and analyze complex physical systems. This exam is typically taken by high school students who have completed or are concurrently studying calculus and have a strong foundation in mechanics, often through AP Physics C: Mechanics. Success can lead to college credit, advanced placement, and a significant advantage in STEM degree programs.

A capacitor initially charged to V0 is discharged through a resistor R. A student plots ln(V_C) versus time and gets slope -5 s^-1. What capacitance follows from the graph?
Three charges sit at the corners of a square of side a: +q at the lower left, +q at the lower right, and -q at the upper left. A fourth charge +q is brought slowly from infinity to the empty upper-right corner. What work must the external agent do?
A rectangular current loop sits in a uniform magnetic field with its magnetic moment initially perpendicular to B. The loop is released from rest. Which statement best describes the initial torque and force?
A tiny electric dipole of moment p is centered at the origin. A detector sits on the dipole axis at r = 8R, where r is much larger than the charge separation. Which leading-order field magnitude should the detector use?
A metal ring is above a long solenoid. The solenoid current upward is increasing, producing upward flux through the ring. Viewed from above, what induced current appears in the ring?
