This study guide covers capacitors, focusing on parallel-plate capacitors. It explains what a capacitor is, including dielectrics, and explores parallel-plate capacitor theory, including capacitance, charge (Q), and potential difference (V). It also discusses calculating capacitance based on physical dimensions and other capacitor geometries (spherical and cylindrical). Finally, it covers energy stored in a capacitor and provides practice questions and exam tips.
