- Capacitor and Capacitance
- The capacitance of a capacitor is defined as:
- Determining Capacitance
- Parallel-plate capacitor:
- Cylindrical Capacitor:
- Spherical Capacitor:
- Isolated sphere:
- Potential Energy and Energy Density
- Electric Potential Energy (U):
-
- Energy density (u)
- Capacitor in parallel and series
- In parallel:
- In series
- Capacitance with a Dielectric
- If the space between the plates of a capacitor is completely filled with a dielectric material, the capacitance C is increased by a factor κ, called the dielectric constant, which is characteristic of the material.
- Gauss’ Law with a Dielectric
- When a dielectric is present, Gauss’ law may be generalized to
