Rectangular Parallel Plate Capacitance
Rectangular Parallel Plate Capacitance Model
Capacitance between the parallel plates is:
The capacitance calculated using this tool is the capacitance between a pair of parallel rectangular plates.
Assumptions and Limitations
Plates are assumed to be flat and parallel over their surfaces.
Plates are assumed to be negligibly thin.
Plates are assumed to be sufficiently large and sufficiently close together that the effects of fringing fields at the edge of the plates may be ignored.
Plates are assumed to be separated by a homogeneous medium having permittivity and permeability.
Permeability of free space: H/m
Permittivity of air: F/m
