You aren’t supposed to use positive polarity AC adapters to power a negative polarity device. Can someone explain why and how that all works?
In: Engineering
If you plug electronics in reverse, current will flow in the wrong places in integrated circuits and they can fry, also components like capacitors can literally explode if plugged in with reverse polarity
Some devices will have protection, others might not be affected at all, but many others don’t and will break
It depends on the device. Most of the time they’ll have diodes that only allow electricity flow in one direction. So it simply won’t work.
If they don’t have diodes then you’ll have electricity flowing the wrong direction, going where it shouldn’t maybe shorting out it will probably explode. If you’re lucky only metaphorically. If you’re not lucky it may do it literally.
