    Interesting bit of trivia. Microwaves don’t actually have “high” or “low” settings. The magnetron, the microwave’s core component, only has two states - on and off. It can’t power the magnetron at 10% power level.

    Instead, the “power” settings just control how often the magnetron is activated. So maybe at full power it’s on 100% of the time. At medium it’s 10 seconds on, 10 second off. At low it’s 3 seconds on, 10 seconds off. That kind of thing. The “power” setting is just a glorified timer.
