A step - up transformer operates on a 230 V line and a load current of 2 A. The ratio of primary and secondary windings is 1 : 25 . Then te current in the primary is

A

15 A

B

50 A

C

25 A

D

12.5 A

Text Solution

Verified by Experts

The correct Answer is:
B
As, `(E_(S))/(E_(P)) =(N_(S))/(N_(P)) =(I_(P))/(I_(S))`
`rArr (25)/(1)=(I_(P))/(2)`
`rArr I_(P)=50A`
