    The applicable relationship is N1/N2 = V1/V2, meaning the ratio of primary voltage to secondary voltage is equal to the ratio of primary turns to secondary turns.

    Here N1 = 1000, V1 = 250, V2 = 400V and N2 = TBD.

    Rewriting the above relationship, N2 = N1 V2/V1 = 1000 x 400/250 = 1600 turns.
