I need to drop 5 volts to 2 volts. After lots of reading I come across voltage divider circuits,
It seems the perfect solution,
I have worked out that I need a 5k resister on feed and a 3.3k resister to earth, which should give me 1.9 volts between the resisters.
Is this right ? what about power consumption ? what wattage resisters do I need ?
I am using a 5 volt 2.5 amp supply, and running a motor from a kids toy,
"second thought" could I use a variable resister to adjust the output volts ?
Is there anything I need to beware of ?
A bit of expert advice would be much appreciated.
Thanks for the advice on LEDs you all, now converted to Piranha, (perfic)

What could possibly go wrong ?
