Determine the capacitance of a circular disk quickly and accurately. This online calculator helps engineers, students, and enthusiasts find the capacitance based on the disk's radius and the permittivity of the surrounding medium. Understand how geometry and material properties influence capacitor design.
Formula:
The capacitance (C) of a circular disk in a uniform dielectric medium is given by the formula:
C = 8 × ε × R
Where:- C = Capacitance in Farads (F)
- ε = Absolute Permittivity of the medium (F/m), calculated as ε = ε₀ × εᵣ
- ε₀ = Permittivity of free space ≈ 8.854 × 10⁻¹² F/m
- εᵣ = Relative Permittivity (Dielectric Constant) of the medium (dimensionless)
- R = Radius of the circular disk in meters (m)
