Induction to change output voltage of DC.

  1. Jul 23, 2009 #1
    I am trying to adjust the output voltage of my 12v DC adapter. Is it possible to wrap the wires of the adapter around a toroid in a closed circuit, and then wrap another wire around the toroid to have the output voltage of this wire decreased, and the current increased?

    From your sketch, you are trying to make a transformer after the 12V adapter. That would only work if the adapter had an AC output. You cannot do that with a DC output.
