My answer about electronics was about E3 and your “it depends” answer is about the other components. I readily admit I do not know what will happen with modern electronics in all those cases. As for your other post about E1 and E2, you are right, there are models for how they are created and propagate.
“My answer about electronics was about E3”
My mistake then, I apologize.
E1 is on the order of 50,000 volts per meter in field strength on the unclassified pulse. Very problematic for electronics.
E3 is on the order of 40 volts per KILOMETER, or .04 volts per meter. This field will not impact any electronics.
However, those field levels can generate a current in the earth hundreds of kilometers deep. This can cause a large current to flow as geologic conditions vary and this is what kills unmonitored and unprotected transformers. E3 does not meaningfully couple to any wires to generate currents.
