In a transformer, the number of turns in primary and secondary are `500` and `2000` respectively. If current in primary is `48A`, the current in the secondary is

A

12A

B

24 A

C

48 A

D

144 A

Text Solution

Verified by Experts

The correct Answer is:
A
As `underset(1)(N)` / `underset(2)(N)` = `underset(1)(I)`/`underset(2)(I)` `adr` `underset(2)(I)` = (`underset(1)(N)`/`underset(1)(I)`) `underset(1)(I)` = `( 500/2000) xx 48 ` = 12 A
