2. Master the definition of electric field strength (via ratio definition) and the principle of superposition, and be able to use electric field lines to describe the distribution patterns of electric fields.
3. Understand the properties of conductors under electrostatic equilibrium, grasp the principles of electrostatic shielding and corona discharge, and apply them in practical life and production scenarios.
4. Understand that work done by electrostatic forces is independent of path, and master the relationship between electric potential energy and work done by electrostatic forces.
5. Master the definitions of electric potential and potential difference, their vector/scalar nature, and apply U = Ed to solve problems involving uniform electric fields.
6. Understand the concept of capacitance, know the factors determining parallel-plate capacitors, and be able to analyze the acceleration motion of charged particles in electric fields.
7. Understand the role of power sources, and the definitions of current and steady current, and be able to explain the formation of current from a microscopic perspective.
8. Master the resistance law of conductors, understand how resistivity changes with temperature, and gain familiarity with superconductivity.
9. Be able to identify volt-ampere characteristic curves and distinguish between linear and nonlinear components.
10. Understand electric work, electric power, and Joule’s law, and be able to differentiate energy conversion in purely resistive versus non-resistive circuits.
