So I have a standard laptop power brick at 19V 3.42A DC.
I need to drop the voltage to 12V and leave the amperage the same.
I went through a chart online here http://www.blackfiveservices.co.uk/fanspeedcalc.php?Voltage=19&Current=4&Target=12
which stated to use a 2.7 OHM resister but...that just doesn't seem right to me.
Can someone with more knowledge on this chime in if they think it'll work?
Thanks!!!
