AP Physics C: Electricity & Magnetism Complete Study Guide (2026 Exam)
Master AP Physics C E&M for May 2026: Gauss's law, circuits, Maxwell's equations, exam format, and study plan.
Short answer: The 2026 AP Physics C: Electricity and Magnetism exam is Thu, May 14, 2026 (12 PM Local) — 40 MCQs, 180 minutes total, hybrid digital (MCQ in Bluebook, paper FRQs).
The 2026 AP Physics C: Electricity and Magnetism exam is Thursday, May 14, 2026 (12 PM local).
Exam Structure
40 MCQs (50%) + 4 FRQs (50%). Same four FRQ archetypes as Mechanics (10+12+10+8 points).
Unit Weights
| Unit | Topic | Weight |
|---|---|---|
| 1 | Electric Charges, Fields, Gauss's Law | 20–25% |
| 2 | Electric Potential | 15–20% |
| 3 | Conductors and Capacitors | 12–17% |
| 4 | Electric Circuits | 17–22% |
| 5 | Magnetic Fields and Electromagnetism | 15–20% |
| 6 | Electromagnetic Induction | 13–18% |
Units 1, 4, and 6 are critical — Gauss's law, RC/LC circuits, and Faraday's law appear every year.
FRQ Tips
- Set up Gauss's law integrals with correct symmetry.
- For circuits: Kirchhoff's rules + calculus (capacitor charging/discharging).
- Show Lenz's law direction before calculating induced EMF.

Frequently asked questions
Should I take Mechanics before E&M?
College Board recommends Mechanics first. E&M is typically taken in the same year or the following year.
What calculus do I need?
Integrals for electric fields and flux, derivatives for EM induction. Multivariable concepts appear but single-variable calc suffices.
Is the exam format the same as Mechanics?
Yes — 40 MCQs and 4 FRQs, 50/50 weighting, hybrid digital, 3 hours.
