    #7546990 - 10/22/07 01:49 PM (16 years, 3 months ago)

hey guys ive looked everywhere and cant find a post on HOW TO hook up your power supply to the potentiometer, can some one tell me which hole to put the wires in?

ive got a 12v power supply with a 12vdc radioshack fan and i just bought a 100k (no idea what that means) potentiometer.

Connect the + to + and the - to the -. + is usually red and - black.
12 vdc stands for 12 volts direct current. 100k stands for 100 kilo ohm, which is the resistance. You'll be getting 12/100k = 0.00012 A = 1.2 mA.
P = U*I = 12*0.00012 = 0.00144 watts on lowest setting
assuming your potentiometer goes from 1-100k, you'll get 0.144 watts on highest setting. So you won't max out your fan, but you'll probably not need to either.

And someone should probably double check my calculations. I haven't done electronics for years.
