My question revolves something I learned my 1st year as an electrician. Electricity always follows the path of least resistance. Using this as a voltage divider, what would prevent voltage drop at the 6v if you hook up a larger circuit with a fair bit of resistance? Why wouldn't more current just take the shortcut through the second 10k resistor to ground, since that would be "easier" than going through your project?
somebody was talking about driving an arduino in a car, and some suggested they use a divider to power it.

So, the best way to run an Arduino is via a three-terminal regulator of some sort
A car's charging system can go up to 14.8V or so when the battery's fully charged, and the voltage will drop below 12V when the engine's not running and the battery's low.
