No, AC has not ended there.
The original AC current is changed from 60HZ AC to 120PPS DC power through the rectifier, through the load, and back from the load as 120pps DC, through the rectifier again and back to 60HA AC, then back to the generator.
There is an unmovable law of electronics: 100% of the current generated from an electrical source always returns to that power source.
I meant that my pitiful knowledge of AC electricity is about tapped out at this simple circuit. Thankfully, I'm almost competent at certain other things.
P.S. Always glad to meet a Freeper who has a "1" as the first digit of their join year and a "7" as the last.
