Wire Pair Capacitance Capacitance Calculators
Wire Pair Capacitance Model
Capacitance between the pair of wires is:
The capacitance calculated using this tool is the capacitance between the wire pair over the wire length. Model accounts for proximity effect of closely spaced wires.
Assumptions and Limitations
Dimensions are in meters.
Wires are assumed to have circular cross sections and to be uniformly spaced over their length.
Wires are assumed to reside in a homogeneous medium having permeability of free space and relative permittivity .
Permeability of free space: H/m
Permittivity of air: F/m
