Dielectric Constant Calculator
Calculate permittivity and capacitance for dielectric materials
Parallel Plate Capacitor (optional)
About Dielectric Constants
The dielectric constant (relative permittivity) describes how a material polarizes in an electric field, reducing the effective field strength and increasing capacitance.
Key Formulas:
- ε = ε₀εᵣ (absolute permittivity)
- C = ε₀εᵣA/d (parallel plate capacitor)
- χ = εᵣ - 1 (electric susceptibility)
- D = εE (electric displacement)
Applications:
- Capacitor design
- High-k gate dielectrics
- Microwave substrates
- Energy storage devices
