Bill,
If the tank cap is of the correct size to produce resonant charging, the
reactance of the cap will neutralize the inductive leakage reactance of the
NST, allowing it to draw more current than its rating. It will actually
draw more current than it will with a direct short. The current limiting
is inductive, and this is what allows the technique to work. The voltage
output can also rise to higher than normal levels using resonant charging.
