i want to lower down the voltage from 13.8v to 8v. i already try using 33ohm 10watt resisitor,but the voltage is still the same,only the ampere got lower down.
be carful uysing the voltage dividor method, because (as I discovered), as soon as you put a load accross the bottom resistor, it puts a resistance in parallel with the resistor, and changes the voltage completly.
Use a regulator, it will not have these problems, and will add a few extra nice features aswell
