    in a center tap transformer wouldn't the peak input voltage be twice the peak output voltage?assuming that the secondary is half the primary length. my textbook says otherwise or can u have secondaries with the same length of the primary an get all the flux to flow from the primary to the conducting secondary?
    reply fast cuz i have xam on monday.

    Depends on whether your text is referring to a half secondary (center tap to either end of the secondary) winding or the full secondary winding.

    If the total secondary winding has half the turns of the primary then the ratio of the primary to the full secondary winding (end-to-end) will be 2:1.

    If you are referring to the center tap to either end of the secondary, then (given the above primary to full secondary winding ratio) the ratio of primary to half-secondary will be 4:1
