GED® Science: Electricity & Magnetism
Electricity and magnetism are two of the most tested Physical Science topics on the GED®. This course builds from the basics of electric charge and current all the way through Ohm's Law, series and parallel circuits, electrical power, the relationship between electricity and magnetism, and how motors, generators, and transformers work. Every lesson uses real-world examples, labeled diagrams, and worked calculations. The practice set covers all GED® difficulty levels with full explanations.
