for line admittances. With such shifting, the numerical values representing
admittances can be directly read.
Inspection of Figures 6.9a and 6.9b reveal that the related impedance and
admittance are on opposite sides of the same Smith chart. The imaginary
parts always have different signs in impedance and admittance charts.
Therefore, a positive (inductive) reactance corresponds to a negative (induc-
tive) susceptance, while a negative (capacitive) reactance corresponds to a
positive (capacitive) susceptance.
