Which resistor do I need? Answered
I am using DC current to power 4 computer fans. I have 3 fans hooked up now that draw out about 560mAh. I need to know what resistor to use to get 12V DC 1440A down to 8V DC .25A. Please respond as quickly and informatively as possible. Thank you in advance.
Note: I got the 1440Amps from subtracting the usage from what the AC adapter puts out. The AC to DC adapter I am using puts out 12V 2Amps. If you can tell me the model number, and/or colour code.
