The ratio of secondry to the primary turns in a trans is `9:4`. If the power input be `P`, what will be the ratio of power output (neglect all losses) to power input

`4:9`

`9:4`

`5:4`

`1:1`

Text Solution

Verified by Experts

The correct Answer is:

Since all the losses are neglected.
so`P_(out)=P_("in")`
