CapacitanceWideStriplineFormula

CapacitanceNarrowStriplineFormula
Units: Farads

Description
The capacitance calculated using this tool is the capacitance between a flat conductor and two equidistant ground planes.

Assumptions and Limitations
Dimensions are in meters.
Ground planes are assumed to be perfectly conducting and of infinite extent.
Conductor is assumed to have zero thickness and to be uniformly spaced between the ground planes.
Conductor and ground planes are assumed to be separated by a homogeneous medium having permittivity e=e0er and permeabilityu=u0.

Constants
Permeability of free space: Formula, Permeability of Free Space H/m
Permittivity of air: Formula, Permittivity of Air F/m
Speed of light in a vacuum: Formula, Speed of Light in Vacuumm/s
