Small-Scale Question Sunday for September 15, 2024

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Nuclear EMP is not the same thing as an electric arc; it's a massive burst of radio waves that induces currents inside devices. Gaps do matter. That's why you need multiple layers, so that there's metal connected between any two given directions (ideally closed circuits, to cancel the magnetic component as well as the electrical one).
