Text Solution

Verified by Experts

The correct Answer is:
B
In step down transformer ,
`underset(P)(V)` gt `underset(S)(V)`
but, `underset(P)(V)`/`underset(S)(V)` = `underset(S)(I)`/`underset(P)(I)`
`therefore` `underset(S)(I)` gt `underset(P)(I)`
So, current in the secondary coil is greater than the primary.
