i wanna bring 12 v down to 4.5
Here's a typical examplehttp://www.electronics-lab.com/articles/LM317/Use a 240 Ohm and a 620 Ohm resistor

how many watts should the resistors and capacitors be?
1/8 watt will be fine.
Can some one please draw me a diagram on how its put togeather. Id appreciate it alot. thank you
LM317 is the perfect answer,but incase you are unable to find it go with a LM7805,it will bring 12 v to 5 v (just connect a resistor to drop 0.5 volts) & you should be good
You should avoid using resistors to adjust the output of a power supply. Use a diode, and let its 0.5..0.7 v forward drop do it instead.
Thank's for the info :)
Use a regulator, not resistors. An LM317 will be perfect
