Why can't I use a voltage divider? Answered
I am working on building my own firework controller. the whole thing will be powered by 6v dc, with the exception of the test circuit this going to run on 1.5v (I am using an optocoupler to separate it from the 6v). I was just going to use 2 resistors to make a voltage divdered to get the volatge down to 1.5. I just read however that "voltage dividers should not be used to supply power to a load". My question is why cant I use this method? When do you actually use this method? and what should I use to properly reduce the voltage?
