    Transformer has 20 windings 100 secondary windings secondary voltage is 25V
    A transformer has 20 primary windings and 100 secondary windings. If the secondary voltage is 25V, find the primary voltage.

    KISS

    The ratio of the windings is the same as the ratio of the voltages.

    Can you figure it out?
