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).

measuring by series mode only.)
