 Reactance (X) and Susceptance (B)
In AC circuit analysis, reactance is represented by the capital letter “X”
which is the imaginary a part of complex impedance. Reactance is the
opposition of a circuit element to a change in the current or voltage, due to
that element's inductance or capacitance which is similar to the opposition
of resistance to current in a DC circuit. In an AC circuit (e.g. a series RLC
circuit) inductance and capacitance may oppose current and are named
reactance measured in units of Ohm (Ω).
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. The latter is the reciprocal of impedance (B=1/X)
and is measured in units of Siemens (S).
