How do I figure out what resistance to select for a pot.
I have 12VDC i/p supply and load is dimmable LED bulb (4Watts, 0.33Amp).
Just as a trial & error, I tried a 1/4 Watts pot with 1M Ohm resistance (audio taper) and there was almost no dimming, I got 0% to 100% dimming in 10 degrees rotation of the knob.
