I need to make a voltage regulator to regulate 12V. Obviously I need to divide that down so I can monitor it. I saw a circuit in a magazine once that used an op amp with a gain of 1/10 to do the dividing. Does this simply sound like a good excuse for a tutorial on op amps, or would the op amp somehow work better than a simple voltage divider?
