A step - up transformer is used on 120 V line to provide a potential difference of 2400 V . If the number of turns in the primary is 75, then the number of turns in the secondary shall be

A

1500

B

750

C

150

D

450

Text Solution

Verified by Experts

The correct Answer is:
A
As, `(V_(S))/(V_(P))=(I_(P))/(I_(S))=(N_(S))/(N_(P)) rArr (2400)/(120)=(N_(S))/(75)`
`rArr N_(S)=(75 xx 2400)/(120)=1500`
