In electrical engineering, susceptance (B) is the imaginary part of admittance. The inverse of admittance is impedance, and the real part of admittance is conductance. In SI units, susceptance is measured in siemens. Oliver Heaviside first defined this property, which he called permittance, in June 1887.
Formula
The general equation defining admittance is given by
where
Y is the admittance, measured in siemens.G is the conductance, measured in siemens.j is the imaginary unit, andB is the susceptance, measured in siemens.The admittance (Y) is the inverse of the impedance (Z)
or
where
Note: The susceptance is the imaginary part of the admittance.
The magnitude of admittance is given by:
