This study guide covers conservation of electric energy in closed systems and its applications in circuits. It explains the relationship between electric fields and work, including the formula W = qΔV and its sign conventions. It also discusses electric potential energy (U), its relationship to electric potential (V), and how it relates to Coulomb's Law and electric field strength. Finally, the guide provides exam tips, practice questions on these concepts, and a scoring rubric.
