    Answer:

    N_P = 40\ N_S

    To reduce the output voltage to 6v in transformers if the input voltage is 240v​, we need to have 40 times as many turns in the primary coil as there are in the secondary coil.

    Explanation:

    The change in voltage of a transformer depends upon the turns ratio of the transformer between secondary and primary coil. Following formula can be used to determine the turns ratio in this case:

    \frac{N_P}{N_S} = \frac{V_P}{V_S} \\\\

    where,

    N_P = No. of turns in the primary coil

    N_S = No. of turns in the secondary coil

    V_P = voltage in the primary coil = 240 V

    V_S = voltage in the secondary coil = 6 V

    Therefore,

    \frac{N_P}{N_S} = \frac{240\ V}{6\ V} \\\\N_P = 40\ N_S

    To reduce the output voltage to 6v in transformers if the input voltage is 240v​, we need to have 40 times as many turns in the primary coil as there are in the secondary coil.
