I am using a 10k digital potentiometer to adjust the brightness of an LED. However, I need to make sure that when I reduce the resistance on the pot, it will not exceed the maximum power ratings.
The max power the pot can handle is 473mW.
So using P = I^2R, we get Imax = 6.88mA.
The battery is 3.3V
From here I am stuck and unsure how to move forward with those values. I have a circuit like this (10k, not 1k): But according to this answer, that circuit seems to be called the 'pot smoker' How can I make sure that I do not blow out the pot? Is there a circuit I can create to put in between the pot and the LED?
