if my 12volt motor running with 12v draws 10amps, am i right in thinking if i put 6 volts on the same motor then it would run at half speed? how would i work out the value of the resistor needed?
i know i need to use ohm's law somehow but it's been a while since i've had anything to do with this and cant remember just how to do it....
thanks
