According to an Oak Ridge National Laboratory technical report (http://web.ornl.gov/sci/ees/etsd/pes/pubs/ferc_Meta-R-320.pdf ), smaller electronic devices are better able to resist the damage caused by an EMP.
I'm at a loss to see why this is true. According to Ohm's law, the current density in a conductor is proportional to the electrical field inside it. If we agree that it is the large and anomalous E field created by an EMP which causes the damage, then it seems like it shouldn't matter how large or small the device is. What am I missing?
