I have inherited a really cool transformer. The markings indicates it is a variable transformer. I've tested it a bit and seems to work as expected. I'm curious about a few things. one is could I use a bridge rectifier to make a DC supply? two is how does it work? My understanding of transformers is it has to have two different windings with a different number of turns to create a voltage difference. sorry about the huge images, i wanted the markings to be clear.
