I'm building a 12VDC circuit powered by eight 1.5V cells in series. It's composed of two main sections; one part runs on 12V, the other part runs on 6V.
Rather than the usual way of using a series resistor to reduce the voltage for the 6V section (which would wastefully consume power), could I instead 'tap' voltage off after the first 4 batteries? Is this a standard way of providing lower-than-full voltage, or is there some reason this wouldn't work?
