The next formulas are used to determine the characteristics of 2-wire balanced lines.
Formula 1
Where:
Z is the impedance in ohm (Ω)
εr is the dieletric constant
D is the distance between wires in centimeters (cm)
d is the wire´s diameter in centimeters (cm)
Formula 2
Where:
C is the capacitance in picofarads (pF)
εr is the dieletric constant
D is the distance between wires in centimeters (cm)
d is the wire´s diameter in centimeters (cm)
Formula 3
Where:
Lx is the inductance in microhenry (uH)
µ is the relative permeability
D is the distance between wire in centimeters (cm)
d is the wire´s diameter in centimeters (cm)
