Electric Charges, Fields, and Gauss’s Law

Electric interactions described through charge, force, and field: charge transfer and polarization, Coulomb forces and vector superposition, fields of continuous charge distributions, electric flux, and symmetry-based applications of Gauss's law. Topics: Electric Charge and Electric Force, Conservation of Electric Charge and the Process of Charging, Electric Fields, Electric Fields of Charge Distributions, Electric Flux, Gauss’s Law.

Electric Potential

Electric interactions described through scalar potential and system energy: pairwise assembly energy, potentials of discrete and continuous sources, line integrals and spatial derivatives connecting potential to field, and energy conservation for charged-particle motion. Topics: Electric Potential Energy, Electric Potential, Conservation of Electric Energy.

Conductors and Capacitors

Conducting materials at electrostatic equilibrium, charge redistribution through contact and grounding, and capacitors as charge and energy stores. Topics: Electrostatics with Conductors, Redistribution of Charge Between Conductors, Capacitors, Dielectrics.

Electric Circuits

Moving charge described through current, current density, resistance, and power, then assembled into circuit models with sources, resistors, meters, and capacitors. Topics: Electric Current, Simple Circuits, Resistance, Resistivity, and Ohm’s Law, Electric Power, Compound Direct Current Circuits, Kirchhoff’s Loop Rule, Kirchhoff’s Junction Rule, Resistor-Capacitor (RC) Circuits.

Magnetic Fields and Electromagnetism

Magnetic fields described through maps, dipoles, material response, and the moving charges that produce and experience them. Topics: Magnetic Fields, Magnetism and Moving Charges, Magnetic Fields of Current-Carrying Wires and the Biot-Savart Law, Ampère’s Law.

Electromagnetic Induction

Changing magnetic flux produces emf and induced currents whose directions follow Lenz's law. Topics: Magnetic Flux, Electromagnetic Induction, Induced Currents and Magnetic Forces, Inductance, Circuits with Resistors and Inductors (LR Circuits), Circuits with Capacitors and Inductors (LC Circuits).
