ELi5: Why do you need to wait 10 seconds to power cycle certain electronics?
In: Technology
Electronics use capacitors, which are essentially little batteries, when you turn things off those batteries will keep it powered for a few seconds, or in the case of some equipment a few minutes.
In essence when turning something off you switch it to a very limited battery backup.
I work in industrial controls, big inverters with huge smoothing capacitors, if you’re working on those, you turn them off completely and go for a coffee to allow the caps to bleed down if you don’t they’re capable of giving you a horrific bite, some of the smaller inverters will take up to 45 seconds to finally turn off totally after power is off.
