Parallel-plate Capacitor Calculator
Note: Dielectric Constant is dimensionless.
Parallel-plate Capacitor formula:
C = K ε0 A/d
where:
ε0: 8.85 × 10-12 F/m
K: The dielectric Constant, dimensionless
A: Plate area, in m^2
d: Plate distance, in meter
C: Capacitor, in Farat
Calculates the capacitance of a parallel-plate capacitor whose opposing plates having same plate area and same small distance from each other.
Kε0 equals permittivity.
