A step up transformer connected to a `220V AC` line is to supply `22 kV` for a neon sign in secondary circuit. In primary circuit a fuse wire is connected which is to blow when the current in the secondary circuit exceeds `10mA`. The turn ratio of the transformer is

`50`

`100`

`150`

`200`

Text Solution

Verified by Experts

The correct Answer is:

`(N_(s))/(N_(p))=(V_(s))/(N_(p))=(22000)/(220)=100`
