How can you reduce output voltage to 6v in transformers if the input voltage is 240v​

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:

where,

= No. of turns in the primary coil

= No. of turns in the secondary coil

= voltage in the primary coil = 240 V

= voltage in the secondary coil = 6 V

Therefore,

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.
