Dan, As I am still learning, there is much about electricity and radio circuits I still have not fully grasped. So let me ask, what to some may be a dumb question.

Once one knows what the required voltage drop should be. What formula (simple I hope) do you use to determine the necessary resistor value in Ohms as well as the required wattage value??? I realize that once I know the appropiate value range, I can then try lowering or raising the resistor value to achieve what I am looking for.
