In a step up transformer, if ratio of turns of primary to secondary is `1:10` and primary voltage si `230 V`. If the load current is `2A`. Then the current in primary is

`20A`

`10A`

`2A`

`1A`

Text Solution

Verified by Experts

The correct Answer is:

`(N_(p))/(N_(s))=(I_(s))/(I_(p))impliesI_(p)=(N_(s))/(N_(p))I_(s)=(10)/(1)xx2=20A`.
