mull982:
In the AC excited application if the value of R is made zero, then there is no decay of the transient component and the AC current is displaced, has a DC component that is constant, by the instantaneous value of the steady state current at the time of turn on. Thus, the maximum peak current would be 2 times the normal steady state peak value.
For most applications in the real world R is not zero or even close in an inductive circuit. Thus, in the near term, 1/2 cycle, the peak current won't be greater than 2 times the peak steady state value and in most cases much less. At t=0 the current is still always 0.
This kind of magnitude within the first cycle after turn on is not something one would describe as inrush. Inrush implies something large in comparison with normal.
