(SIEMENS) The term $\omega C$ represents the capacitive susceptance $(B_C)$ in an alternating current circuit.
In an $AC$ circuit,the capacitive reactance is given by $X_C = \frac{1}{\omega C}$.
The unit of capacitive reactance $(X_C)$ is Ohm $(\Omega)$.
Therefore,the unit of $\omega C$ is the reciprocal of Ohm,which is $\Omega^{-1}$ or Siemens $(S)$.
