I know one can limit current in ac circuit using a capacitor, but do not know how in dc circuit. What I want to accomplish is take the power coming from a 12 volt car battery and limit it so I have 12 volts at 20 ma output?

Last month I was told that when the world ended there would be NO math. Smile
