I think just like many things, we would be looking at bell curve type results.
There would be some areas very heavily hit where nothing electronic works. Not the grid, not the cell towers, not computers or even most transistorized radios.
But there would in all likelihood be other areas where the damage would be much less severe.
A study of the whys/wherefores is something that could only be done following the event.
A study of the whys/wherefores is something that could only be done following the event.We do this already, it's called ESD testing and EMI susceptibility testing.
I get the impression I'm talking to a civilian on your end?
Even consumer stuff today gets ESD testing performed on it ... I've had equipment take direct strikes by lighting even; on a GE "MASTR PRO" repeater the arc marks were obvious, and included an 'entry' into the 'squelch' circuit ... I lost a single TO-5 cased transistor there ... EMP is NO WHERE near as intense. Read the EPRI paper ...
