Hi Guys,
Cant get this right, I have 4 AA batteries total voltage 6v, 2500 mAh each. Then I have 2 devices one needs 6v another needs 3v power supply so I did basic voltage divider from 2 resistors.
10R resistors burned my hand.
Then I tried 1K resistors, I got voltage divided and multimeter shows 3v, However when I connect the load - in my case small microcontroller module to 3v output and servo to 6v output, the 3v output goes down to 1.5v as soon as I connect the module and that is not enough to power up the microcontroller.
Do you know why this might happen? am I choosing wrong resistors?
Thank you
