How to drop 9 volts to 3 volts at 32 ma Answered
Hello, I am a new B here. I would like to use a 9 volt battery to power lights for my RC car. The led lights operate at 3 volts 32 ma. What size resistor will I need to make the voltage drop. Will this also control the current so I do burn up the lights. The lights are somewhat expensive so would like to get it right the first time. Thanks for anyone's help.
