Units: Farads

Description
The capacitance calculated using this tool is the capacitance between two coplanar flat conductors.

Assumptions and Limitations
Dimensions are in meters.
Conductors are assumed to have zero thickness.
Conductors are assumed to be embedded in a homogeneous medium having permittivity e=e0er and permeabilityu=u0.

Constants
