I like the calculations, but what is your basis for the data for the Carrington event? Were there meters that took good scientific data then? Think about it, harnassed AC electrial energy was still a few decades down the road. As I stated in an earlier post, would voltage of that magnitude (as you stated) be enough to generate enough power and heat to catch a DC cell on fire? Electronics utilizes wiring too. What is to prevent enough from intruding into that wiring to inflict the damage so many fear?
” As I stated in an earlier post, would voltage of that magnitude (as you stated) be enough to generate enough power and heat to catch a DC cell on fire?”
if you have a 500mile DC telegraph line, you’re looking at a voltage on the order of 25000v being induced. that would be plenty
