Here is a fairly basic question that I think I know the answer to, but I need some verification. If I take a 12 volt battery rated at 5 amps and put a resistor in line to drop the voltage to 6 volts (indicated by a VOM), will the amperage double to 10 amps or stay at 5 amps? Are there any considerations that I need to be aware of if I am trying to power a 6 volt device?

Thank you.
