What is the formula one needs to use in order to figure out what size resistor I need (in DC) for a particular voltage in (12 volts) to the desired voltage out (6 volts). The application is this: My wife purchased these luminara candles that take two C batteries (3 volts) from QVC. There are 12 of these candles. To put batteries in these ALL THE TIME to keep them lit would cost a small fortune. I have a 12 volt transformer (120v AC to 12v DC). I don't mind putting two together in series, but 4 seems a bit much. I don't want there to be anymore than one other unit to be a factor should something fail. Otherwise, this will start to seem like trying to figure out which light bulb went out in Christmas tree light strings! ...how do you spell PAINFUL!
To be sure, this is probably already on here. I've been searching for a bit, but with the amount of posts in all the forums... it's just exhausting to try and find. If that sounds lazy, I apologize. I just have better things to do with my time and I'll find this information elsewhere. (Not upset/bitter, just stating facts.) Thanks ahead of time should anyone wish to respond to this presumably easy question based upon all the other things that are on here! GREAT site, by the way!!! I can only hope to understand HALF of the stuff on it by the time I die! Blessings.
