Title: 12v to 9v
Post by: SimplyDead on January 14, 2012, 11:10:51 PM
what resistor would I need to make a 12v to a 9v 2200mah going to be trying the lcd screen in xbox 360 mod

You don't want a resistor.

You want a voltage regulator, I am unable to recommend what type unless you tell us the current needed (in mA or A).

trying to power a lcd screen and it needs 9v,s but theres only 12v 5v and 3.3v on the motherboard so a regulator will downstep it from a 12v to 9v?

Use three 9v regulators in parallel to get 3amps of current output. http://www.parts-express.com/pe/showdetl.cfm?Partnumber=7809 (http://www.parts-express.com/pe/showdetl.cfm?Partnumber=7809)


PLEASE USE A REGULATOR!!!



but... you can cheat and get away with not using a regulator or a resistor... I do NOT recommend this but hear me out.

Use the +12v as Positive and the +3.3v as ground...

ok why?...

12 - 3.3 = 8.7

You will have an 8.7v potential difference.

we are not talking in logic, we are talking in real world practicality,

use a voltage regulator.

Interesting... This is why I wish I knew more about electricity.
