    resistor and voltage didivion

    Yeah I had come to the same conclusion re 12v battery. I have access to a 5 volt ps, going to try the buck regulator approach. Thanks again John

    resistor and voltage didivion

    Hi Dana just had a thought, would it not be easier to just take a 12 battery and use a series voltage dropping resistor to get 2.2 volts? Regards john

    resistor and voltage didivion

    I need to halve the voltage of the 3.4v out put and the 5 v out put to run a single cell electrolyzer. Optimum voltage for a single cell is between 1.7 and 2.2 volts. It asks about 20 amps.

    resistor and voltage didivion

    Hi, I need to divide my voltage on a power supply. If I have a 3.4v out put and a 5v out put what resistors do I need to halve these two? Thanks in advance.:)
