Surge/ground/lightning

In assessing the high frequency content of any wave form, including a
lighning pulse, the rise time is not significant. The actual
calculation is based on the slew rate, or slope of the wave form. A
lighning pulse of 1.2 microseconds has a slew rate of many thousands of
amps per microsecond. That is why there is much high frequency content
in a lightning pulse.

Lightening don't give a **** where it goes.

You don't understand electricity. It voltage rise not amps. Amps is
Voltage / resistance. It's amps that kill people. How much depends on
body resistance and the voltage supplied.

Umm--when a current passes through a load there is voltage developed
across the load--remember ohms law?
