You first: What are your qualifications to even understand answers about EMP, electronics, electrical generation and distribution system?
I’m a bright layman who took physics for BA majors.
Not my strength. I’m not an idiot regardless of what many think. LOL.
Seems to me the basics are fairly simple . . . intense radations of some type of ‘RF’ for lack of better term . . . cause impulses in wires to build up—including heat—that overloads the ability of the wires or components to hold together and continue functioning.
Is that a wrong understanding?
Purportedly there are
EMP WEAPONS IN SPACE that make such doings much easier and more ‘selectable’ than the nuke blast type.
