## Answers ( )

Answer:There are 45 turns in the secondary coil.

Explanation:Given that,

Input potential of the lamp,

The output potential of the lamp,

Number of turns in primary coil,

We need to find the number of turns needed on the secondary coil. We know that the ratio for a transformer is as follows :

So, there are 45 turns in the secondary coil.
