So I think we've established that you connected the two transformers as shown in Fred's power supply, not as you had originally described it. In other words, you connected them back-to-back (i.e., tied the secondaries together).
You should be able to figure out how this would work, keeping in mind that a transformer works in both directions.
You basically built a 1:1 isolation transformer consisting of 2 xfrmrs.
Why would you think you'd be able to use this to save electricity? You can't create something out of nothing.
Fred's circuit uses the transformers to isolate his power supply from the power line for safety reasons. Otherwise, he'd just connect his bridge rectifier directly across the incoming line ("mains").
And yes, I'd be curious to know what you were trying to accomplish too.
i thought i could connect the output of 2nd transformeR to a TV Or DvD player..etc [bcz it takes only 12v and convertrts it to 230vAC so cant i use it to save some bill?..maybe not,.)
