AP Physics C: Electricity and Magnetism expands upon the content presented in AP Physics C: Mechanics, and is divided into five areas. The first is electrostatics. Students will be expected to understand the concepts and types of charge, and use Coulomb’s law to calculate and analyze a force’s magnitude and direction. This unit also covers the concepts and properties of electric fields and electric potential, Gauss’ law, and miscellaneous forms of charge. Second, conductors, capacitors, and dielectrics will be reviewed. Students will be expected to know the mechanics and nature of electric fields in relation to conductors; in particular, the process of charging by induction. The role, functions, and electric fields of capacitors will also be discussed, and students will need to understand the qualities and functions of parallel-plate, cylindrical, and spherical capacitors. Students will need to be proficient in explaining the effect of dielectrics on various types of capacitors.
Next, AP Physics C: Electricity and Magnetism delves into an expansive unit on electric circuits. Students will be expected to know the definition and properties of electric current, conductivity, resistivity, and resistance in order to better understand and describe their relationships. Then, steady-state direct current circuits will be taught. Students are tasked with developing a familiarity with the behavior of both series and parallel combinations of resistors, the properties of real and ideal batteries, and the methods of connecting voltmeters and ammeters. Both Ohm’s law and Kirchhoff’s rules are introduced, and students must be able to accurately apply each to figure out an unknown current, resistance, or voltage.
Magnetic fields are the field’s fourth area of focus, and this unit will teach students about the forces on moving charges, current-carrying wires, and long current-carrying wires extant within magnetic fields. Ampere’s law and the Biot-Savart law are introduced, and students will learn to use them to relate a magnetic field’s strength and discover the contribution that a current-carrying wire has on a magnetic field, respectively. The course concludes with a unit on electromagnetism. It begins with an exploration of electromagnetic induction, including Lenz’s law and Faraday’s law. It moves on to cover inductance in both LC and LR circuits, and ends with a review of Maxwell’s equations.
