As orksecurity said 5 years ago
"As others have said: Not safely, not easily, and even if you had the right resistor, a full-wave rectifier, and capacitors you're going to get a lot of 60Hz noise on the line. Plus, voltage will vary as the amount of current the thing you're powering draws varies. Bad solution all around.""If you need a 12V power supply, use an isolated, regulated 12V power supply circuit."
BTW If you do not know enough to specify the current you should not continue in this project, to avoid making those who love you cry over your body ashes !!
the answer is yes. but more probably it may not be that useful for high rated loads it cannot drive high power loads.The circuit is as simple as converting 12-0-12v of transformer to 12v by means of bridge rectifier here also you can use high power diodes to convert.later on you may get a voltage of around 230v pulsating dc which can be converted to 12 v by potential divider method.connect R1 an R2 in series and output across R2 and its voltage id R2/(R1+R2).
