Consider an inductor in series with a resistor. In sinusoidal steady state, the combination has an impedance Z = R + jωL. The admittance is given by (1/Z) = (R-jωL)/(R

^{2}+(ωL)

^{2}), and if R is zero, it is simply -j/(ωL) as expected. But the admittance can be broken into conductance and suseptance, so the calculated admittance Y = G+jB = 0 - j/(ωL).

But I was expecting G = infinity!

Clearly I am confusing exactly how and when these quantities are defined. Any help would be appreciated.
