ELI5: Why is it recommended that we wait a little bit after turning something off to turn it back on?

Also why can we restart PCs since this contradicts this recommendation?

Most electronics contain capacitors. Capacitors act like little buffers to even out current in a system. A bit like having a header tank in a plumbing system. Think of them like tiny batteries that are constantly charging and discharging.

When you turn off an item, the charge in the capacitors doesn't go away straight away. You have to wait for a few seconds to allow it yo dissipate. The charge can be enough to mean that certain buffers or bits of memory aren't properly reset, so without waiting, the restart alone doesn't always fix it.
