not realy, so if you have a 9v batery conected 2 a LED and anothe LED trough
a switch are you saying that whan you swithch the LED on and of thereby
changing the voltige, i dont think so. Also a ful bridge rectifyer makes DC
out of ac using 4 diodes so looks like this
_ _
/ \ / \ someting like that and even smothing it out with a capaciter it
still has a woble to it IT IS NOT AC! AC it usual referd to as going neg to
pos to neg to pos ect
in a syne wave but sighn wavre is usealy considerd AC (sepends on how
sighnifican change in Volitige is 60 V of change whith in 10000 V is not that
much.)
