I don't have much experience with electronics, I'm simply trying to get (at least what I think) is a fairly simple circuit running.
I've got a blower fan that I need to get running. It uses 12VDC at 4.3 amps. I've got a DC converter that converts 120VAC to 19VDC, but that's too high. I want to step down the voltage from the converter to around 12 volts DC, and I was thinking simply using a resistor might work, though I'm none too sure how the calculations are worked out. I tried an Ohm's law calculation and arrived at that I would need a 2ohm resistor for this, but I'm not sure.
