Secondary current at any frozen instant in time varies along the entire
length of the coil.  (in the nature of 1/4 wave resonators)  The maximum
instantaneous current occurs at the base or ground connection and the
minumum occurs at the top when the voltage output of the coil is at maximum.

For small coils, the peak base current is just an amp or two and really big
systems may see base currents on the order of 100 amps or more.  Much is
determined by the top load capacitance, usually a toroid.
