Susceptance - Biocrawler (74 words)
In electrical engineering, the susceptance (B) is the imaginary part of the admittance.
In SI units, the susceptance is measured in siemens.
Note: The susceptance is NOT the inverse of the reactance.
What is susceptance? - a definition from Whatis.com - see also: B (395 words)
Susceptance (symbolized B) is an expression of the ease with which alternating current (AC) passes through a capacitance or inductance.
Conductance and susceptance combine to form admittance, which is defined in terms of two-dimensional quantities known as complex numbers.
As the inductance of a component increases, its susceptance becomes smaller negatively (that is, it approaches zero from the negative side) in imaginary terms, assuming the frequency is held constant.
