I have a 1k ohm rheostat that has a 25W power rating, and a current rating of 0.15 amps.
I got it because I was running a 12v/24v circuit at 1amp draw. I just looked at the power rating of 25W and thought it would be OK in my circuit. However, that's a low current rating (which I did not notice till just now). I have not used the rheostat yet, but I am guessing it will not handle the 1amp current even though it would be within the power rating.
Please confirm. Thank you.
