Why is it some North American plugs have 3 prongs while some have 2?

I am assuming it is due to requiring more electricity but I’ve had broken 3 prongs work with just 2

Reddit won’t show me the other 4 comments for some reason, so I may be just repeating the same thing as others, but it has nothing to do with how much electricity an appliance uses. It has more to do with the grounding requirements of said appliance. If there are exposed metal chassis parts that *may* become energized in the event of a short circuit, they will be grounded, which utilizes the third prong. The device will function without this safety ground, but if something inside shorts to ground, well, you’re on your own.
