Susceptance

Extracted from the Wikipedia article Electrical susceptance.

In electrical engineering, susceptance ( $B$ ) is the imaginary part of admittance ( $Y = G + jB$ ), where the real part is conductance ( $G$ ). The reciprocal of admittance is impedance ( $Z = R + jX$ ), where the imaginary part is reactance ( $X$ ) and the real part is resistance ( $R$ ). In SI units, susceptance is measured in siemens (S).
