High voltage Joule thief

Yahoo Answers: What resistor would I use to reduce 12v to 9v?

you want to use a resistor for reduce a voltage without knowing your 9V device power consumption. reduction of voltage on a resistor depends on how much current passes through it. if your device wants 0.5 amperes to run, you want a 6 ohm resistor in series with your device to reduce input voltage by 3 volts. you can calculate other values you have with formula: V=R.I were V is reduction of voltage on resistor and R is resistor's value and I is Current passes through your resistor.
