please provide values of resistors for bringing 220v to 12vdc
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).
