Unit 10 · Electric Force, Field, and Potential
Chapter 10.4
Capacitors
Two metal plates a hair apart, and suddenly a circuit can store energy like a spring. Slide a sheet of plastic between them and it stores even more.

By the end
- 01Compute the capacitance of a parallel-plate capacitor from its geometry and dielectric constant
- 02Relate stored charge, potential difference, the uniform field between the plates, and stored energy
- 03Predict how a dielectric changes capacitance, field, charge, and energy, battery connected or removed
- 04Analyze the projectile-like path of a charged particle moving between the plates
