Re: 200 vs. 1200 ohms in laptop fan




"Nick"

Is a small fan for a laptop computer basically in working order if its
resistance measures about 1200 ohms +/- 4% when it should be 200 ohms?
I don't know the proper design tolerance.


** Computer fans contain an electronic drive circuit - they are not
resistors.



The fan is labeled for 12VDC and 0.06A, which is how I arrive at the
200-ohm calculation. I measured it using a cheap multimeter.


** Forget the multimeter.

Connect the fan to a 9 volt radio battery - see if it spins.
