So Indeed it does occur, and it's a hair-pulling predicament when you do not know this.
That leaves unregulated power materials. This can be very like the AC motor circumstances above other than that a transformer decreases the AC voltage, that is then ordinarily rectified and filtered to generate bumpy DC voltage.
