Reactance (X) and Susceptance (B = 1/X) Formula
Background Reactance measures the imaginary part of
Impedance (Z) caused by capacitors or inductors.
Susceptance is the reciprocal of Reactance and
measures the imaginary part of Admittance (Y),
which is the reciprocal of Impedance.
Note
Reactance and Susceptance is only shown for their
relation to impedance. Reactance and Susceptance are
not measurable features of the LCR-800 series.
