I hope this has a simple answer.
I would like to drop 24v to 12v and think a potential divider would be the best way.
Just 2 resistors the same size, but what value?
I have tried to use a 7812 as I was under the impression that the motor I wanted to run for a short period of time was only 500mA but it burned the regulator out.
I have used a 12v battery and measured the motor and it goes up close to 1A now it is installed and running under load.
Is there a reason for what ever value the resistors are? I assume I would be ok with 21 watt resistors?
I have found 2 x 330 Ohm resistors, I am not at the site so just fit and test is not practical but I just wondered if there is a reason for resistor value when calculating potential divider design
Thanks.
