    Answer:

    1.97 V

    Explanation:

    Applying

    N1/N2 = V1/V2………………. Equation 1

    Where N1 = primary turns, N2 = Secondary turns, V1 = primary/input voltage, V2 = secondary/output voltage.

    make V2 the subject of the equation

    V2 = V1(N2/N1)…………. Equation 2

    Given: V1 = 118 V, N1 = 480 turns, V2 = 8 turns.

    Substitute into equation 2

    V2 = 118(8/480)

    V2 = 1.97 V.
