ClarityHow to use this tool
- Enter plate area, plate separation, relative permittivity.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
Input reference and sample values
Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.
| Input | Format and units | Sample |
|---|---|---|
| Plate area | Numeric value. Unit: m². Must be greater than zero. | 0.01 |
| Plate separation | Numeric value. Unit: m. Must be greater than zero. | 0.001 |
| Relative permittivity | Numeric value. Must be greater than zero. | 1 |
Result for these sample inputs
8.85418781e-11 F
Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Capacitance = ε0 × relative permittivity × area/gap; ε0 ≈ 8.8541878128 × 10⁻¹² F/m.
Using plate area = 0.01 m², plate separation = 0.001 m, relative permittivity = 1, the result is 8.85418781e-11 F. Change these example inputs to match your task; use the method above to check each step.
What to keep in mind
Neglects edge fields. Dielectric properties may depend on frequency and temperature. Ideal-component calculation for study and estimation. It does not select safe wiring, protective devices or component ratings for an installation.
