Parallel-plate Capacitor Calculator

Dielectric Constant:
Plate Area:
Plates Separation Distance:
Capacitance:

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.
