Hi everyone, I've a device which says on the lable DC12V 0.6W, I want it to work on a output AC16V 1000mA power supply. I've came out a thought, but don't know if it works. for AC to DC, I can use 4 diodes and a filter cap to built a Bridge Rectifier to convert it to DC. for it able to work on 16V as the device says DC12V 06.W, so use ohm's law. the current = 0.6W/12V=0.05A. the resistance=12V/0.05A=240ohms 16V resistance=16V/0.05A=320ohms this is the resistance need to works on the 16V power. so the original 12V resistance is 240ohms and the 16V resistance is 320ohms. the difference is 80 ohms. so what I means is add a 80ohms resistor in series to the device then it can be used on a 16V power supply??? I'm just beginner, have limited knowledge of electronics, maybe it completely wrong. can anyone tell me will it works or not? or anyone knows how to do? please tell me. thanks in advance.
