Physics - DC Circuits - High School and AP Physics

This course is one of several Mousseau Physics courses designed for students in high school physics, AP Physics, and introductory college physics. In this course we focus on direct current circuits. Students will study electric current, voltage, resistance, Ohm's law, electric power, series circuits, parallel circuits, combination circuits, and Kirchhoff's laws.

The videos and resources include clear lectures, circuit diagrams, demonstrations, and worked out example problems. Students will practice simplifying circuits, identifying what is the same and what changes in series and parallel branches, using equivalent resistance, applying conservation of charge and energy, and solving multi-step circuit problems. The course is designed to make circuit analysis more organized and less like guessing.

This course is a strong fit for high school physics students, AP Physics students, and introductory algebra based college physics students. It does not require calculus. Students who struggle with circuits often need a clearer method for tracking current, voltage, and resistance rather than simply memorizing isolated rules.

By the end of the course, students should be more confident reading circuit diagrams, predicting current and voltage behavior, solving series, parallel, and combination circuit problems, and explaining why different circuit arrangements behave differently. These skills are also useful preparation for more advanced electricity and magnetism topics.

Students can work straight through the course as a full unit or use individual lessons as targeted support alongside a class. The videos are built to be paused, rewound, and practiced with pencil and paper, so the course works well for homework help, test review, exam preparation, or rebuilding a topic that did not fully click the first time.
